Challengers of the Unknown by Jack Kirby SC

At last, DC collects Jack Kirby's run of adventure epics from Showcase #6, 7, 11 and 12 and Challengers Of The Unknown #1-8 in a single paperback volume! These are the tales that introduced Ace Morgan, Red Ryan, Rocky Davis and Professor Haley-four men living on borrowed time, determined to face-and overcome-adversity in the form of monsters, aliens and would-be world conquerors!
