The Rebel Legion are currently running multiple auctions on eBay to benefit the Make a Wish Foundation.
"In 2012, the Rebel Legion decided to do a limited set of sketchcards of our members to commemorate Celebration VI in Orlando Florida. 14 world renowned and extremely talented artists generously donated their time and skills to create these one of a kind pieces of art. Each piece features a Rebel Legion member in their approved Star Wars costume. Once the art was completed it was compiled into sets only available to Rebel Legion members. With the approval of Lucasfilm™, the original art for the cards was to be auctioned off to benefit the Make-A-Wish Foundation® in hopes that the funds would bring joy to a child in need.
Please help the Rebel Legion help kids in need by bidding on these one of a kind pieces of art."
