Here's an incredibly cool set of superhero woodcut art created by artist Brian Reedy. The set features Marvel and DC characters like Wolverine, Batman, Thor, Superman, Spider-Man, Aqua Man, and even Hellboy. I did some woodblock art for a class once, and holy crap, it was hard! Reedy seems to have a handle on it, though. This stuff is fantastic.
Each one is 12"x24" woodblock printed on 20"x30" rice paper with deckle edge. If you like what you see, you can purchase them in his Etsy store.
