In the original promotion for The Brightest Day Aftermath: The Search For Swmp Thing, while Batman and Superman were present on the cover and we worked out the foreground fellow was John Constantine, the other dark figure was a mystery.
But when John was officially revealed, so was Zatanna…
Not any more. In previews printed in certain DC titles today, Zatanna has been replaced with… Hawkman!
Just think, all that drawing of extra background foliage for nothing, now covered by big wings…
UPDATE: As pointed out in the comments, looking at the Bat logo, Batman switched from Bruce to Dick to Bruce again…
