Charlton's Children of Doom by Sergius O'Shaugnessy (Denny O'Neil) and the late great Pat Boyette is a full length comic book story with a blend of full color and black and white pages. The adventure featuring a holocaust, space and time traveling with more than a few mutants wandering around is a compelling story, especially given the period it was produced in and the audience it was aimed at. Very much a product of the Cold War era with a rather obvious Dr. Strangelove reference as the world faces an uncertain future in the age of the Atom Bomb. Originally published in September 1954.
