After looking at hundreds of comic book covers, it becomes quickly apparent that not every cover is 100% original. Whether done intentionally or even underhandedly, there’s something about uncovering these “swipes” that adds a new element of fun to reading and collecting comics.

The 400th issue of Batman was illustrated by a host of great artists including Art Adams, Brian Bolland, John Byrne, Mike Grell, George Perez, Steve Rude and Bernie Wrightson. The cover featured a Bill Sienkiewicz piece and there was even a special introduction by Stephen King.
