I was kidding. Wasn't he originally bird man?
All his life, Bob Kane maintained that he was inspired by several different sources to change the name “Bird-Man,” but this claim is a thoroughly fallacious subterfuge. As we’ll see in our next chapter, one source -- and one source ALONE -- inspired the change of the prefix of the new hero’s name from “Bird” to the mysterious and nocturnal sounding “BAT.”
Then, as recorded in The Steranko History of Comics, Finger recalls, "I got Webster's Dictionary off the shelf and was hoping they had a drawing of a BAT, and sure enough it did. I said, 'Notice the ears! Why don't we duplicate the ears?' I suggested [Bob] draw what looked like a cowl. I had suggested he bring the nosepiece down and make him mysterious and not show any eyes at all. I didn't like the wings, so I suggested he make a cape and scallop the edges so it would flow out behind him when he ran and would look like bat wings. He didn't have any gloves on. We gave him gloves.”
The next problem: What SETTING should the writer and artist use for their new hero’s first front cover image? Again, let’s copy the superstar -- Superman. The cover of the then-recent issue of Action Comics (#7, Dec. 1938, shown left) showed Superman dragging a terrified criminal high above the city.
Imitation being the sincerest form of flattery, Finger and Kane (or possibly Kane on his own) may have decided their NEW hero should do exactly the same. So Kane drew a similar scene, substituting the figure he had swiped from Flash Gordon for Superman. Kane's drawing, which was to be used almost unaltered for the cover of Batman's first adventure, looked something like this:
