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.

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.

I came from Canada when I was about 10 years old, and our family settled in Cleveland, Ohio.

Clark Kent, I suppose, had a little bit of Harold Lloyd in him.

And I agreed the feeling of action as he was flying or jumping or leaping - a flowing cape would give it movement. It really helped, and it was very easy to draw.

I think initially we wanted to use the first letter of the character's name. We thought S was perfect.

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.
