We carry Jim Woodring's Weathercraft at the comic book store. Pretty awesome if you're into the really weird surreal artists. I've always liked R. Crumb, so I actually recommended to my boss that we order some of these crazy Fantagraphics books like Weathercraft because they're in that same vein.
I would recommend the work of Al Columbia if you like Jim Woodring, but you wish his work was a little more terrifying. Actually, a lot more terrifying. Great work, but unbelievably creepy.
