The comic shop where I work (Orbital Comics) currently has an exhibition of postcards doodled, scribbled and drawn on by various artists, performers, writers, actors, and musicians with connections to the Comic Book and Sci-Fi universe. The postcards are being auctioned on eBay to raise funds in aid of Crusaid and to spread awareness of HIV/AIDS. Read more about it HERE. Ebay auctions of the postcards here. Of note is an Optimus Prime one by Andy Wildman and a couple of great pieces by Staz of Wonder Woman and Supergirl. Check them out and spread the word around, it's all for charity. Anyone in London, England over the weekend can see them in the gallery of the shop.
