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 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.

In this drawing we just let our imagination run wild. We visualized Superman toys, games, and a radio show - that was before TV - and Superman movies. We even visualized Superman billboards. And it's all come true.

I drew a picture on the back of a calendar in pencil. In those days they used to give out free calendars, I had no art paper, so I took whatever else I could.

Jerry picked up the technique of visualizing the story as a movie scenario; and whenever he gave me a script, I would see it as a screenplay. That was the technique that Jerry used, and I just picked it up.

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.
