The super-speedsters of two worlds race into adventure in this new collection of tales Learn how police scientist Barry Allen, the Flash of the 1960s, first crossed paths with his predecessor, Jay Garrick, the Flash of the 1940s, in this hardcover featuring THE FLASH #123, #129, #137, #151 and #173, collected in DC's Deluxe Edition format for the first time.
These are the stories that first established the science fiction concept of parallel universes in DC Comics, as the Flash learned of a way to use his super-speed to travel across dimensions to Earth-2, home of an older generation of heroes who began their crime-fighting careers in the 1940s. It all begins in Flash of Two Worlds, one of the most famous tales from the Silver Age of Comics, and led to subsequent tales in which the two super-speedsters teamed up to battle Captain Cold, the Trickster and more of the Flash's Rogues Gallery of villains.
