The Hero Initiative, a non-profit that raises money to help comic book creators in need, put together a project where a 100 artists each contribute a new cover illustration to Ultimate Spider-Man #100. The new covers will be auctioned one-by-one to raise funds. Comic Book Resources has put an almost complete gallery of all the covers. Check it out here. It's a pretty cool project and its fun to see how all of these artists depict spidey. Especially those that have never drawn spidey before. Like Neil Gaiman! We even get a new McFarlane spidey illustration. Although, it just looks like a variation of his Spider-Man #1 cover.
