first anti-Communist story; pg. 2 panel 2 swiped from cover of MODERN COMICS #70
When reprinted in #71 the last page is removed and the last panel of page 4 is re-lettered. Original dialogue "He sure moves fast for an old geezer! Wait a minute! He's no old geezer! His beard's coming off! Maybe he's a spy or something! I'm going after him!" New dialogue "Hey, Mister!" and the policeman thinks "All right, fella, if you don't want to pick up your change it's hour business" and Chop Chop thinking "Me never take another picture!". Last page of the original story has Chop Chop being taken in by the police and recognized as a member of the Blackhawks.
