The original splash page has been modified to create this cover. The blurb "Iron Fisted Justice" replaces the original text box, more windows are added around it, and the legs of the figures have been slightly extended. Information from Frank Motler.
The original splash page has been replaced with a new splash, in addition to other minor changes made to make Rocketman into Zip-Jet, etc. Art credits changed from Ruben Moreira as originally indexed, based on the reprint of the original story in Golden-Age Greats (AC, 1994 series) #1, information from Jerry Bails' Who's Who, and Frank Motler.
Art credits revised from Ruben Moreira to Al Plastino, confirmed by Bill Black in Golden Age Men of Mystery (AC, 1996 Series) #8 (1998).
