Grant Morrison discusses the cover to Batman and Robin #16

Issue Sixteen This was both mine and Frank Quitely’s finale on the BATMAN AND ROBIN title, and the cover, like so many of the others, had been planned back at the beginning of the run and stayed fairly close to the original intention. This was the first cover to feature our two Batmen — pinch-hitting Dick Grayson and the returned Bruce Wayne — together in action with Robin, and I’d imagined a kind of hierarchical “totem pole” stack of heroes with one above the other.
