As a science fiction fan, I have long been very familiar with the various themes in the field. The superman theme has been one of them ever since Samson and Hercules. I just sat down and wrote a story of that type - only in this first story, the Superman was a villain.
A couple of months after I published this story, it occurred to me that a Superman as a hero rather than as a villain might make a great comic strip character in the vein of Tarzan, only more super and sensational than that great character. Joe and I drew it up as a comic book.
