I had to produce a complete page - or two or three - in one day. I took a lot of pride in my work, and I hated to do a mediocre job. Evidently, some of the writers enjoyed my work best of all for that very reason.

Jerry often says that Slam Bradley was really the forerunner of Superman, because we turned it out with no restrictions, complete freedom to do what we wanted; the only problem was that we had a deadline.

I started young but at every turn, listening provided a foundation for my leadership. I can say categorically that all the really excellent leaders I have known were, in my view, excellent listeners.

I was mild-mannered, wore glasses, was very shy with women.

Jerry and I always felt that the character was enjoying himself. He was having fun: he wasn't taking himself seriously. It was always a lark for him, as you can see in my early drawings.

Jerry reversed the usual formula of the superhero who goes to another planet. He put the superhero in ordinary, familiar surroundings, instead of the other way around, as was done in most science fiction. That was the first time I can recall that it had ever been done.

In the beginning, we had a great deal of freedom, and Jerry wrote completely out of his imagination - very, very freely. We even had no editorial supervision to speak of, because they were in such a rush to get the thing in before deadline. But later on we were restricted.
