Concept artist Henrik Sahlstrom has created this great set of noir-style Batman character art. The characters featured here include Batman, Catwoman, The Joker, and The Riddler. I love this series, and I hope the artist does more.
Batman: Mask of the Phantasm Mondo anniversary variant poster by Phantom City Creative. Hands down, the animated series of Batman was the best iteration of the superhero next to Nolan's version. Such a gem of a film that demonstrates that.
Check out this amazing set of black and white Batman art created by Deviant Art user Sean Gordon Murphy. This artist has some great stuff, and I'm sure I'll be sharing more of it with you. He has a pretty cool style.
