We've seen the rise of "voluntourism" and eco-tourism of the luxe variety (think private bugalow in Figi, not hippie yurt). But giving back and luxury travel have rarely been an oft-cited pair. Until, that is, CharityFolks.com came on the scene, crafting unique travel plans including exclusive meet-and-greets like an evening with the cast of The Sopranos, then sending along the proceeds to charity. Each trip functions as an auction, so you'll need to get your virtual paddle up if you want to claim jaunts like a weekend at the Newport Jazz Festival, or luxe accommodations at Vail. The site hosts more traditional charity auctions as well, which have been written about here in the past, but if you planned to stay at the Four Seasons whilst touring Provence anyway, why not do it through an organization that will then donate on your behalf to UCLA's Jonsson Cancer Center?

Nineteen to-covet designers including Oscar de la Renta, Manolo Blahnik, Alberta Ferretti and Christian Louboutin are teaming up with Warner Brothers and Swarovski to reinvent Dorothy's ruby slippers to commemorate the 70th anniversary of The Wizard of Oz. This time, we're not in Kansas anymore. Based on some of the designer sketches we've seen, we're talking Swarovski-fied, ruby red protect-me-from-the-evil-witch stilettos. Basically what sweet little Anne Hathaway could have used in The Devil Wears Prada.

Each designer will craft a mere two pairs, and the shoes will make their debut September 4 during New York Fashion Week, posing in Saks Fifth Avenue's window before moving on to Miami's Art Basel and further appearances throughout 2009. The iconic slippers will then be auctioned off with proceeds going to the Elizabeth Glaser Pediatric AIDS Foundation.

When contemporary art cult fave Shepard Fairey started "campaigning" for Barack Obama, he created original collages assembling inspiring portraits of Obama above titles like HOPE, PROGRESS and CHANGE. We saw them silkscreened on tee shirts worn by the likes of Ryan Phillippe that soon became impossible to get, selling for thousands on eBay. Now for the true connoisseur -- of politics and art -- the rare opportunity exists to bid on one of the original three pieces, OBAMA HOPE. Currently at $60,000, the piece is being auctioned by Westport, CT-based CharityBuzz, which will donate profits to the Rush Philanthropic Arts Foundation, providing access to the arts to disadvantaged urban youth. CharityBuzz will accept bids until July 24, but if you miss this potentially revolutionary piece of art, you can at least order the sticker version online at Sticker Robot. Big spender yours truly just snagged ten of them.

On August 2nd, RM Auctions will sell of a stunning selection of classic cars, including a coveted Mercedes-Benz Gullwing (above), at the annual Meadow Brook Concours d'Élegance in Michigan. The event takes place at Meadow Brook Hall, the historic 110-room Tudor Revival mansion built in the 1920s by auto heiress Matilda Dodge Wilson. In May, RM set a world record by selling the 1961 Ferrari formerly owned by James Coburn which we wrote about for $11 million.

The Mercedes, a beautiful black 1956 300SL, is estimated at $575,000 - $675,000. We prefer it to the other, slightly more expensive Mercedes on offer, a 1936 500K three-position drophead coupe by Corsica, est. $600,000 - $750,000. Also included in the stunning sale: a 1937 Bugatti Type 57 Ventoux Coupe, est. $475,000 - $575,000; a 1930 Isotta-Fraschini 8A Convertible Sedan by Castagna, similar to the one featured in Sunset Boulevard, est. $400,000 - $600,000; and a 1954 Jaguar XK 120SE Roadster, est. $80,000 - $110,000. See the gallery for more.

The price of magazines is going up all the time but this is really excessive, now there will be a gold and diamond cover of a women's magazine. A gold and diamond covered version of of the style magazine, Kohl, will be auctioned for charity in October and is expected to bring in more than than $10,000. ITP Lifestyle, the publisher of style magazine Kohl, partnered with Emirates-based jeweler Damas to create the unique cover which features 622 diamonds. The magazine will be auctioned to raise money for the Rashid Pediatric Therapy Center in Dubai. The gilded front cover features Indian actress Katrina Kaif and it took the craftsmen more than 86 hours to hand-apply layers of gold leaf to a specially-treated edition of the original magazine.

On July 26, London auction house Bonhams is staging a sale of Porsche and Lotus motorcars at the Silverstone Classic, one of the UK's premiere motor sport events. Unlike some auctions, the Silverstone sale skews to the more affordable side, without any million-dollar motorcars. In fact, most lots are priced below $100,000, yet there are several beautiful examples of highly collectible classics and contemporaries from the two famous marques.

For instance, the gorgeous 1959 Porsche 356B coupe pictured here, which is estimated at only $36,000 - $40,000 and is in impeccable condition. Also on offer: a legendary 1973 Porsche 911 Carrera RS touring coupé, est. $220,000 - $260,000; a 1972 Porsche 911 3.0-litre rally car, est. $80,000 - $100,000; a 2007 Lotus Exige Cup 255 coupé, est. $90,000 - $110,000; a 1967 Porsche 911 2-litre coupe, est. $64,000 - $72,000; and a 1973/2006 Lotus Elan +2 Spyder Zetec coupe, est. $40,000 - $50,000.

Finally some good news for eBay. The company which just lost a big suit against LVMH in France is having better luck on this side of the Atlantic. The AP reports that a federal judge in Manhattan has ruled in favor of eBay over Tiffany & Co. in a trademark infringement lawsuit. In the suit Tiffany & Co. claimed that eBay's sale of counterfeit goods resulted in trademark dilution, false advertising and unfair competition. When the case opened last November, James Swire, a lawyer for Tiffany, said that a full 75% of 325 items that Tiffany has bought on eBay through a buying program the company started in 2004 were counterfeit.

But the entered by Judge Richard Sullivan at the U.S. District Court for the Southern District of New York on Monday puts the onus for policing its brand on Tiffany. The ruling said the company failed to prove that eBay was liable for the sale of the goods.

As in other cases, eBay argued that it is merely a host for buyers and sellers. That argument didn't fly in France but but Judge Sullivan said in his opinion that "Given Tiffany's choice to sue eBay, rather than individual sellers, and this Court's conclusion that eBay does not continue to supply its services to those whom it knows or has reason to know are infringing Tiffany's trademarks, Tiffany's claims against eBay must fail."

If the decision had come back in Tiffany's favor it would have been a decisive blow for eBay, showing that they were liable for the actions of their sellers. But this decision, combined with the LVMH lawsuit, which puts forth a different view, show that right now there is no clear answer in the question of who is responsible for counterfeit goods on eBay. As always, if you are buying on eBay, caveat emptor.

For the consumer who wants to avoid counterfeit merchandise on eBay, a little research can make a big difference. Looking at the feedback score of the seller and reading the comments can give you some insight into the seller's history. A feedback score of at least 99 percent is best. Also when you are in the seller's history click on the past auctions. If this seller has sold a lot of similar or even identical branded items this is a big red flag. Also, sadly, if it sounds too good to be true and the price is really low you may be looking at a fake.

If you missed out on one of those $100,000 Asprey shotguns we told you about that were auctioned off at Christie's in May, not to worry - Bonhams is holding its own Sporting Guns sale in London on July 30 where you can bid on some extremely fine pieces at a fraction of the cost. In actual fact, the highest priced guns at the Christie's sale were made by Holland & Holland, and there are several fine examples of their craft in the Bonhams sale. For instance, a 1947 12-bore 'Royal de Luxe' sidelock ejector shotgun with foliate-scroll engraving and gold inlays (above), est. $32,000 - $40,000, in its original leather case.

Also on offer: A fine lightweight 1934 12-bore over-and-under shotgun by J. Woodward, in a leather case, est. $40,000 - $50,000; a 10-bore 'Premiere' single-trigger over-and-under shotgun by E.J. Churchill, est. $20,000 - $30,000; a 1905 12-bore self-opening sidelock ejector gun by Purdey, est. only $10,000 - $14,000; and several fine vintage guncases including one stunning example executed in crocodile skin, est. only $400 - $800. See the gallery for pix.

On July 16, Sotheby's in London is staging a stunning sale of Important Watches. The top lots are all of course Patek Philippes, but there are some prime timepieces from the likes of Rolex, Panerai and Cartier as well. Leading things off pricewise is an exceptional platinum minute repeating perpetual calendar tourbillon Patek with retrograde date, phases of the moon and a black dial, est. $700,000 - $900,000.

From there prices drop dramatically and there are some deals to be found. We're particularly fond of this 1945 steel Patek chronograph with register and tachometer, est. only $50,000 - $80,000. On the Rolex front there's a rare 1972 stainless steel Submariner made for the British Royal Navy, est. $50,000 - $70,000, and a stainless 1983 Daytona cosmograph, est. $28,000 - $36,000.

An ultra-rare 1955 Jaguar D-Type (above), the first production example ever made, is being auctioned off by Bonhams during the Goodwood Festival of Speed in Sussex, England on July 11. The car, which carries an estimate of $4 - $5 million and has a colorful racing history, is one of the most coveted sportscars ever produced; a similar one was owned by Steve McQueen.

Renowned entrepreneur and broadcast veteran Art Astor is selling off part of his famous car collection in Anaheim, California this weekend. The sale, conducted by RM Auctions, mainly features American cars with a few classic imports of the kind we're partial to thrown in. We're particularly fond of this 1970 Jaguar XKE Series II Roadster, for example, which with an estimate of only $40,000 - $60,000 is something of a bargain. Also included in the sale: a 1927 Rolls-Royce Phantom I "Playboy" roadster which was used as a movie car and has been driven by Bette Davis and Robert Redford, est. $175,000 - $250,000; a 1968 Jaguar XKE Series I.5 2+2 Fixed Head Coupe, est. $30,000 - $40,000; a 1961 Jaguar XK150 3.8 Roadster, est. $80,000 - $120,000; a rare 1941 Chrysler Town & Country Nine-Passenger Estate "woody" wagon, est. $250,000 - $300,000; and a 1954 Chevrolet Corvette Roadster. est. $125,000 - $150,000.

Not to be outdone by archrival Christie's, Sotheby's is staging its own major Contemporary Art auction in London on July 1st. With total pre-sale estimates topping $130 million, the event is being billed as "the highest value summer sale of contemporary art ever held by Sotheby's in Europe." The untitled Jean-Michel Basquiat painting belonging to Irish rockers U2 that my colleague Deidre Woollard mentioned earlier this month is a top draw in the auction, with an estimate of $8 - $12 million.

Other highlights include two important works by Francis Bacon: Figure Turning, painted 1962, est. $20 - $30 million, and Study for Head of George Dyer, painted in 1967, est. at over $16 million. Rounding out the other notable big-ticket items are Richard Prince's Overseas Nurse, 2002, est. at $8 - $12 million - more than the current Prince auction record; and Andy Warhol's 1964 Large Campbell's Soup Can (pictured right), est. $5 - $7 million. Also of interest: tennis great John McEnroe is selling his 1986 Warhol portrait with ex Tatum O'Neal, est. only $500,000 - $700,000. See the gallery for images.

Last month we reported that there was to be an auction of apparel from The Sopranos. The results from the June 25 event are in: Twenty-five outfits worn by James Gandolfini's alter ego raised $187,750 and benefited the Wounded Warrior Project, a nonprofit that aids wounded soldiers in Iraq and Afghanistan. Gandolfini attended part of the Christie's auction with a soldier from the project.

The highest bid was for a faux-bloodstained outfit that Gandolfini wore in a scene when Tony is shot by a demented Uncle Junior: the black and beige short-sleeve polo shirt, a tank top and black pants brought in $43,750. The next highest bid was $21,250 for a four-piece costume that included a blue, red and yellow striped robe and boxer shorts that the actor wore in numerous episodes. Other top-selling outfits included a tan cotton bathrobe with lavender trim and 'S' insignia on the breast pocket that was featured in the pilot when Tony fetched the morning paper and fed the ducks in his pool, which raised $13,750.

All of the outfits were authenticated by Gandolfini, and many had the original production tags attached. See a sampling of the auctioned items in the gallery. See the entire lot and prices realized here.

On Monday, Bonhams will auction off an astounding collection of vintage motorcycles worth $2 million at the Royal Air Force Museum in London. The sale represents the largest single-owner collection of motorbikes ever to come to auction; all 300 machines are from the Professor Fritz Ehn Motorcycle Museum in Austria. Our favorite lots are two wicked - and wickedly fast - British-made Vincents: the 1955 998cc Black Prince, pictured here, est. $56,000 - $64,000; and a 1952 998cc Black Shadow, the fastest road-going vehicle of its time, est. $44,000 - $56,000.
