I had no idea that Oprah Winfrey had a car collection but she does and she's auctioning off three vehicles from her private collection: a red 1954 Mercedes-Benz 300 SL Gullwing formerly owned by the DuPont family, a 1988 Rolls-Royce Corniche II Convertible given to her by John Travolta and a 1997 Aston Martin DB7 Volante to benefit her school in Africa. The action will be held by by Gooding & Company and will take place at Pebble Beach on Saturday, August 16th and Sunday, August 17th. The auction catalogs are available for $100, which includes viewing and auction admission for two, while general admission is set at a price of $40 per person.

The 1954 Mercedes-Benz 300 SL Gullwing is estimated to sell for $600,000-800,000, the 1988 Rolls-Royce Corniche II Convertible is estimated at $70,000-100,000 and the 1997 Aston Martin DB7 Volante is estimated at $50,000-65,000.

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?

Tonic Generation offers just one product in many styles (T-shirts) but donates on average 40 percent of its revenue. The organization partners with designers and causes to create limited edition products in these areas: the environment, education, social welfare and poverty. Luella Bartley recently designed four T-shirts with names like Stag, Scary Douglas, Pagan Sun, and Robin. Each has been designed especially for Tonic. Made of a 70-30 bamboo/cotton blend, the fabric does not harm the environment and has been produced according to ethical practices. Tonic is similar to iGive in that you can choose your cause and track your impact. Read the FAQs for more info on how it works!

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.

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.

Rihanna also her own charity, The Believe Foundation, which also benefits children.

It couldn't be more true that in order to have a healthy world we have to have healthy children, and Healthy Child Healthy World is a non-profit organization that makes that principle their main aim by working to protect our youth from harmful environmental exposures. Working through education, laws, governmental agencies, advocacy, and spreading awareness of environmental issues this charity is a no brainer because not only are they helping kids but they're also helping the environment (something we could all be doing more of).
