Batman co-creator Bob Kane's personal copies of early Batman comics are up for auction. They have holes in them.
Those searching for pristine editions of Detective Comics #27 or Batman #1 will have to look elsewhere. These are copies of Detective Comics #27-45 and Batman #1-3 that were bound by DC Comics for editorial reference — as you can see, there’s a row of holes down the left — and later given to Kane. Still, the colors remain vibrant.
