The Newsboy Legion by Joe Simon & Jack Kirby

Set in the early 1940s, The Newsboy Legion is the first of Joe Simon and Jack Kirby's very successful "kid gang" comics, featuring a group of scrappy boys who work together to stop crime in their home of Suicide Slum. Watched over by adult hero The Guardian - a.k.a. policeman Jim Harper - The Newsboy Legion battle crime through their own newspaper reporting, taking on crooked politicians, slum lords, fifth column agents and much more.
