About this Collection

This hardcover Archive Edition collects the earliest adventures of the Challengers of the Unknown, reprinting the team's debut and initial stories from Showcase #6-7 and Challengers of the Unknown #1-2. Created by Jack Kirby and Joe Simon, these 1950s tales follow four adventurers who, having cheated death, dedicate their lives to exploring the unknown and battling bizarre threats. The volume showcases the high-energy, monster-filled storytelling that defined the pre-Marvel Kirby-Simon partnership.
