The Flash was one of my favorite superheroes in 1960-1961...I was especially rocked when The Flash #123 came out in ’61, and the cover featured both the Barry Allen Flash, and the alternate world Flash, Jay Garrick.
That issue introduced the concept of Earths One and Two to the DC Universe, and it was a genius move on the parts of DC editor Julius Schwartz, and writer Gardner Fox. Schwartz and Fox, as well as artist Carmine Infantino, had all worked for DC Comics (then called “National”) during the 1940s. In the days of my youth I read every fanzine I could get my hands on, and wanted to see the early versions of the DC/National characters I liked.
The Flash story below, from All-Flash #27 (1947) is drawn by Martin Naydel with story credited to Robert Kanigher. The villain, the Thinker, does his criminal acts while throwing a variety of gases around. He would have been unacceptable to me had I seen the story in 1961. No costume! What kind of superhero comic book villain goes out without a costume? Perhaps having just broken out of prison the Thinker hadn’t the time between his escape and gassing people to shop for a good costume.
