If you've purchased any (or all) of the Sheldon comics, which ones are they? Have you purchased any of the limited-edition artist collection? If so, share your image with us (photos would be great)! I'd love to see what everyone has gathered.

As for myself, I only have the first 3 books, none of which are artist editions. I plan on picking up the latest collection soon, but the artist editions are already gone. Anyone willing to give up their copy?
