I have a personal definition of cartooning, which is, simply, "imaginative drawing." Anything you're drawing that is not in front of you but is a mental construct that you want to express in a drawing is, to me, a cartoon.

When I started formulating the first Frank comic, I knew I wanted it to be something that was beyond time and specific place. I felt that having the characters speak would tie it to 20th-century America, because that would be the idiom of the language they would use, the language I use.

I think that cartoons have a lot more power than they're given credit for.

A tree is an incomprehensibl e mystery.

Oh, I was never a very big Jim Woodring fan. I've never thought his work was that great.

Real shapes and real patterns are things you would observe in nature, like the marks on the back of a cobra's hood or the markings on a fish or a lizard. Imaginary shapes are just that, symbols that come to a person in dreams or reveries and are charged with meaning.

The books that I do, the stories I write - I'm glad I'm able to do them, but they will quickly be swallowed up by the sands of time. Sometimes it frustrates me that I'm not able to do bigger, more important, more significant things. I guess you have to be content to do whatever it is you can do.
