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

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 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.

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