Endorsements, pranks and obscenity in the Superman comics

The Superman group of comic books is superendorsed. A random sample shows on the inside cover of the endorsement of two psychiatrists, one educator, one English professor and a child-study consultant. On the page facing this array is depicted a man dressed as a boy shooting a policeman in the mouth (with a toy pistol). This is a prank—"Prankster's second childhood." In the story there is a variant of the comic-book theme of a girl being thrown into the fire: "Her dress will be afire in one split second! She'll need Superman's help!"
