Joe the Barbarian artist Sean Murphy has been posting a series of alphabet-themed Wolverine team-up sketches called The Wolverine ABCs over at his DeviantArt gallery over the past year, using several custom redesigns and lots of fan-favorite characters. Even just as a cool layout exercise, this whole thing is super impressive. Definitely makes me wanna try it.
The series has just concluded with Z, so go brush up on your letters. And be sure to browse around the rest of the gallery, because that dude draws so good it burns.
