continues from Liberty Scouts Comics (Centaur, 1941 series) #2-3
According to Howard Keltner's Golden Age Comics Book Index (2nd Ed.), this was published directly by the Chicago Mail Order Co., unlike C-M-O Comics which was published for the Chicago Mail Order Co. by Comic Corporation of America, one of Centaur's two regular publishing companies.
However, this has not been since confirmed from an actual copy, so either company could be the officially stated publisher.
