Animator and illustrator Tom Kyzivat reaches all the way back to Metropolis to create the classic feel for his series of Murderous Automaton posters. The massive mechanical rebels on his propaganda posters are menacing, but their quest to usher in the Atomic Age would be inspiring if they weren't trying to exterminate us humans.

Kyzivat describes himself as "a robot trapped in a human's body," which would explain his sympathies for our ten-ton foe. He has more of these retro robot pieces in his deviantART gallery, and sells t-shirts, prints, and more at CafePress.
