The pointless but fun covers continue with their excellent art. You really wish the cover artists had been assigned to draw inside stories!
The Prankster, Lex Luthor and Mr. Mxyzptlk (then known as Mr. Mxyztplk--big difference!) appear in this splash but barely in the story itself. These were, along with The Toyman, probably the biggest thorns in the Man of Steel's side by this point.
Robin had his own series by this point and even Superboy has turned up in the adventures of Superman when he was a boy.
The Boy Commandos were looking less and less as if they were drawn by Simon andKirby by this point. Since they hadn't been lately, this is no surprise.
