What the comic book covers say
A typical sample has inconspicuously above its crime title, "A force for good in the community!" and underneath that in a small circle, "Crime does not pay," and then in a square, "TRUE criminal case histories!" and, in smaller type, hard to read, the words "Dedicated to the eradication of crime!" Average, normal boys have often told me that if they read such signs at all they know of course that they are only "eyewash" intended to influence parents and teachers who have no time to read the whole comic book.
The cover of this sample depicts a corpse with blood on his mouth, with the killer who has just beaten him to death beside him.
