Special Edition, Superman

A brief, two-issue DC series from the mid-1940s, Special Edition, Superman paired the Man of Steel with a rotating cast of other costumed heroes—including Batman and Robin—in all-new team-up adventures. Written primarily by Bill Finger and Don C. Cameron, with art by Ira Yarbrough and Pete Riss, the series offered an early glimpse at the kind of crossover storytelling that would later define the superhero genre. Though short-lived, it stands as a notable wartime-era experiment in shared-universe publishing.
