World's Finest Comics #149

In "Part I: The Game of Secret Identities!", Superman grows uneasy about the possibility that his secret identity might be exposed, prompting him to enlist Batman and Robin for help. With their assistance, he uses an encephalographic instrument to test whether anyone can uncover his true identity—leading to a tense, mind-bending challenge that puts even the Dynamic Duo to the test.

In a delightfully absurd twist, Super-Turtle answers a mine’s emergency whistle and dives underground to save two trapped miners—only to be handed a bill for four dollars in union dues for his trouble. The story’s playful blend of superhero antics and workplace satire shines through in its offbeat logic and whimsical take on bureaucracy.
