Here's a fantastic new set of 1950s Batman Rockabilly badassery from artist Denis Medri. This time around he shows off some new character designs for Killer Croc, Bane, Catwoman, Poison Ivy, and Robin. There's some pretty rad art in this new set, and I still want to see this concept brought to life at some point.
