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

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 did all the work at the beginning up until the point where I couldn't handle the increasingly heavy art production burden alone. I needed, and got, assistance.

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.

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

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