Ghost World, Daniel Clowes. That Roy Lichtenstein guy is alright, but sometimes the real comic book artists make the best pop art. the Ghost World comic was made into a very good live action movie, which got an Oscar Nomination for best screenplay.
todd solondz's 'happiness' - poster art by dan clowes. I asked Clowes about this one and he told me he was happy to illustrate any movie poster. he'd gladly have illustrated a movie poster with Gabe Kaplan in it.
