One day I called Bill and said, 'I have a new character called the Bat-Man and I've made some crude, elementary sketches I'd like you to look at. ' He came over and I showed him the drawings. At the time, I only had a small domino mask, like the one Robin later wore, on Batman's face. Bill said, 'Why not make him look more like a bat and put a hood on him, and take the eyeballs out and just put slits for eyes to make him look more mysterious?' At this point, the Bat-Man wore a red union suit; the wings, trunks, and mask were black. I thought that red and black would be a good combination. Bill said that the costume was too bright: 'Color it dark grey to make it look more ominous. ' The cape looked like two stiff bat wings attached to his arms. As Bill and I talked, we realized that these wings would get cumbersome when Bat-Man was in action and changed them into a cape, scalloped to look like bat wings when he was fighting or swinging down on a rope. Also, he didn't have any gloves on, and we added them so that he wouldn't leave fingerprints.
