"I always enjoyed doing monster books. Monster books gave me the opportunity to draw things out of the ordinary. Monster books were a challenge — what kind of monster would fascinate people? I couldn’t draw anything that was too outlandish or too horrible. I never did that. What I did draw was something intriguing. There was something about this monster that you could live with. If you saw him you wouldn’t faint dead away. There was nothing disgusting in his demeanor. There was nothing about him that repelled you. My monsters were lovable monsters."
