French artist Grégoire Guillemin just tipped us off to his latest work. Of course, you may remember Guillemin as the one behind these amazing retro-modern supehero illustrations. He's back with Paper Heroes 2, a follow-up to his popular Paper Heroes series where he takes famous superheroes (or villains) and gives them the "construction paper" treatment. Only thing is, they're actually made with the help of some very familiar software. As he says, "It's not real paper cutting, it's Illustrator forms transformed with paper material in Photoshop." Here are our favorites from the full series.
