Luthor, the Prankster and the Toyman join forces against Superman in the cover story from issue 88 (March 1954), by Woolfolk, Boring and Kaye.
The three villains bump into each other at an amusement park. They agree to team up, but this consists of each executing a plan of theirs, with the two other two acting as back-ups.
There is some creativity in the robberies, but all three plans fail.
While Luthor continues to appear regularly, and the Prankster returns early the following year in Superman’s Pal, Jimmy Olsen, this is the first time the Toyman had appeared in four years, and it would be another ten before he returned. His hair is significantly shorter in this story than previously depicted.
