The seed for the Crisis on Infinite Earths was planted in the universe altering Silver Age tales contained within this volume.

As any fan of comics knows, EC comics still represent the best of Golden Age writing and artwork.

Collects THE BRAVE AND THE BOLD #28-30, JUSTICE LEAGUE OF AMERICA #1-8 and MYSTERY IN SPACE #75, and includes the classic tales “Doom of the Star Diamond,” “The Slave Ship of Space” and “Starro the Conqueror!”

These are the stories that first established the science fiction concept of parallel universes in DC Comics, as the Fastest Man Alive learned to use his super-speed to travel across dimensions to Earth-2!

Stories in this volume include "The Martian Monster," in which a 9-year-old boy befriends a Martian in the woods and asks him to kill his stepmother ― but the "Martian" convinces him that it’s really his father who he should target.
