Here we have an extremely rare set of hand drawn production used Warner Bros storyboards from the Pinky and the Brain animated series (the two bottom right storyboards are from the animaniacs I believe). I don't think I've ever run across hand-drawn storyboards from the show. If you're a collector this is kind of a must have.
Storyboards are where the story starts for these cartoons. Each one is roughly 8 by 15 in!!
