Hitler's back. A mad scientist thought he could reform him; make Hitler a productive member of our future society. He was wrong. Now, the only thing standing between mankind and total oblivion is Albert Einstein. Einstein has hand picked the greatest minds in history to face off against this great evil. But who will prevail the latest iteration of The Third Reich? Or the Heroes of Science!

Annotations and commentary

Panel 1
At long last a crowd scene. There's a neck-bearded nerd that will eventually become a recognizable character and Leonardo da Vinci is in the back dancing with two Leather Daddies.
Also, I'm quite fond of my take on George Washington. Note the huge phat chornic blunt and the giant bong. Believe it or not George Washington wrote extensively about growing cannibus. Not just for hemp ropes and shit, either. He seperated out the male and female buds, which as I understand it, is what makes THC potent enough to mean anything. George Washington was a pot head.
Panel 3
Fat, neck-bearded guy is talking to a Monarch Henchman! Could they be #21 and #24 from Venture Bros, the best little Johnny Quest parody in the west?
