"Gotham High Concept Art" by Jeffrey Thomas and Celeste Green3
2 A Batman made up of batman insignia. That is all.
3 Gotham High was a very real proposed animated series which (perhaps thankfully) never got past the concept art stage. Nevertheless, I admire the creativity that went into this youngified approach to Batman's Rogues Gallery. From left to right: Clayface, Two-Face, The Penguin, Killer Croc, The Riddler, Batgirl, Batman, Scarecrow, Catwoman, The Joker, Harley Quinn, Poison Ivy, Bane and Mr. Freeze. You can check out more concept art here. I think that - all things considered - given the consistently high quality of Batman cartoons, from Batman: The Animated Series to The Brave and The Bold, this might have actually been not-terrible. As it is, it's a curious and amusing artifact.
