"Suicide Slum Comics" is a delightful sham comic produced by the Newsboy Legion themselves within the the Star Spangled Comics classic "Cabbages and Comics" by Joe Simon and Jack Kirby.
The story has Big Words, Tommy, Gabby and Scrapper get the big idea to create and distribute their own comics since they see such success for funny books all around them.
They do just that, with each member contributing a panel or two (a process in keeping with the studio approach used in comics at that time). But it turns out the fantasy story they concoct bears too close a resemblance to a real crime and the boys find themselves in a tough spot only The Guardian can rescue them from.
A great glimpse behind the scenes, sort of, by Simon and Kirby. This one is a raucous and entertaining yarn, one among many.
