Showcase Presents Challengers of the Unknown #1

This massive black-and-white volume collects the earliest adventures of the Challengers of the Unknown, reprinting their debut in Showcase #6–7 and their subsequent run through Challengers of the Unknown #1–8. Created by Jack Kirby, the original foursome—Ace Morgan, Red Ryan, Prof Haley, and Rocky Davis—are adventurers who survived a deadly plane crash and dedicate their lives to facing impossible dangers. The collection also includes the team's appearances in other DC titles from the late 1950s and early 1960s, showcasing Kirby's dynamic art and the team's foundational role in the adventure-comics genre.
