You can score a piece of rock history and help a good cause by bidding on items at the Stand Up to Cancer charity online auction to honor the fifth anniversary of Fashion Rocks, a runway show/concert that kicks off the annual Mercedes-Benz Fashion Week in New York. Auction items include an autographed Gibson guitar signed by all the performers and presenters of Fashion Rocks, a Duffy “Kissed and Be Kissed” concert package presented by Nivea, a two-week internship at Giorgio Armani and many more incredible offers. Just log onto www.ebay.com/fashionrocks from September 5–15 to place your bids. The best part of the auction is that thanks to eBay Giving Works, 100% of the proceeds go to benefit Stand Up to Cancer. Tune into CBS on Friday, September 5 to see the concert, featuring Justin Timberlake, Beyoncé, Mariah Carey, Rihanna and many others.
