Columbia Comics, definitely one of the more obscure comic-book companies of the 1940s, was the home of Skyman. I kinda like his costume, though I'm curious to know what he shoots out of that water pistol he's holding in his hand.
Skyman first appeared in 1940's BIG SHOT COMICS, but apparently didn't get an origin story until he debuted in his own title. From SKYMAN #1, this splash is (I believe) by writer Gardner Fox and artist Ogden Whitney. Both men went on to long careers in the comics business; Fox as the longtime scripter of DC's JUSTICE LEAGUE OF AMERICA (among a myriad of titles) and Whitney at Richard E. Hughes' American Comics Group, where he created the cult classic Herbie the Fat Fury.
