The 1960s adventures of the Flash that introduced the Scarlet Speedster to his Golden Age predecessor, Jay Garrick, are collected in DC's Deluxe Edition format for the first time.

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.

Born in 1911 in Brooklyn, New York, Gardner Fox was probably the single most imaginative and productive writer in the Golden Age of comics. In the 1940s, he created or co-created dozens of long-running features for DC Comics, including the Flash, Hawkman, the Sandman, and Doctor Fate, as well as penning most of the adventures of comics' first super-team, the Justice Society of America. He was also the second person to script Batman, beginning somewhere around the Dark Knight Detective's third story. For other companies over the years Fox also wrote Skyman, the Face, Jet Powers, Dr. Strange, Doc Savage and many others—including Crom the Barbarian, the first sword and sorcery series in comics. Following the revival in the late 1950s of the superhero genre, Fox assembled Earth's Mightiest Heroes once more and scripted an unbroken 65-issue run of Justice League of America. Though he produced thousands of other scripts and wrote over 100 books, it is perhaps this body of work for which he is best known. Fox passed away in 1986.

The man most closely associated with the Silver Age Flash, Carmine Infantino began working in comics in the mid-1940s as the artist on such features as Green Lantern, Black Canary, Ghost Patro,l and the original Golden Age Flash. Infantino lent his unique style to a variety of superhero, supernatural, and Western features throughout the 1950s until he was tapped to pencil the 1956 revival of the Flash. While continuing to pencil The Flash, he also provided the art for other strips, including Batman, The Elongated Man and Adam Strange. Infantino became DC's editorial director in 1967 and ultimately its president before returning to freelancing in 1976. Since then he has penciled and inked numerous features, including the Batman newspaper strip, Green Lantern Corps, and Danger Trail.
