ON MAURICE SENDAK:

Believer: How did you find your artistic style?

Maurice Sendak: It's spontaneous combustion. I don't know what's going to work until I start to draw. It is so out of your hands it is amazing. It just started to happen. Bumble-Ardy was a little boy many years ago and now he's a pig. I don't know why. There's so much I don't know about the procedure.
