Irwin Hasen drew the cover for All-Star Comics #37, featuring the Justice Society of America's first battle with the Injustice Society of the World. Hasen, the regular artist for Green Lantern, created Wildcat and later they syndicated comic strip Dondi. "There was no sense of being in hallowed halls or anything," he said of his days at DC when I interviewed him a few years ago. "We were just little kid artists who were happy to be getting paid do what we loved."
Alongside major headliners, DC's early anthology comics featured a lot of neat old characters who, sadly, have disappeared from collective memory. The King, by Gardner Fox and Harry Lampert, got the cover spot on Flash Comics #5 (May, 1940). The "lightning-fast action, mystery, and adventure" also included stories featuring The Whip, Cliff Cornwall, and Johnny Thunder. Besides that, The Flash saved an artist from being rubbed out by a greedy art collector, and Hawkman foiled a kidnapping.
This is a great scene from Justice League of America #104. Apparently it's cleaning day at the JLA Satellite, with Batman divvying up chores to Green Arrow, the Flash, Black Canary, Aquaman, Superman, the Atom, and Hawkman. Len Wein wrote the story, and the art is by Dick Dillin and Dick Giordano.
