Secret Identity showcases rare and recently discovered erotic artwork by the most seminal artist in comics—Superman's co-creator Joe Shuster. Created in the early 1950s when Shuster was down on his luck after trying to reclaim the copyright for Superman, he illustrated these images for an obscure series of magazines called Nights of Horror, sold under the counter until they were banned by the U.S. Supreme Court. A murder trial, juvenile delinquency, anti-comics crusader Dr. Fredric Wertham, and the neo-Nazi Brooklyn Thrill Killers gang all figure into this sensational story.

The discovery of this artwork and the story behind it by historian Craig Yoe reveals the "secret identity" of this revered comics creator, and is sure to change the way we look at Shuster and his creations—Clark Kent, Lois Lane, Lex Luthor, and Jimmy Olsen—forever.
