When Superman debuted in 1938, he ushered in a string of imitators--Batman, Wonder Woman, Captain Marvel, Captain America. But what about the many less well-known heroes who lined up to fight crooks, super villains or Hitler--like the Shield, the Black Terror, Crimebuster, Cat-Man, Dynamic Man, the Blue Beetle, the Black Cat and even Frankenstein?

These and other four-color fighters crowded the newsstands from the late 1930s through the early 1950s. Most have since been overlooked, and not necessarily because they were victims of poor publication. This book gives the other superheroes of the Golden Age of comics their due.
