Detective Comics #237

This November 1956 issue of Detective Comics poses a tantalizing question right on its Sheldon Moldoff cover: could Robin be replaced? Batman stands clipboard in hand, coolly evaluating a trio of Robin-costumed boys putting their acrobatic skills to the test — swinging, tumbling, and vaulting — while the current Boy Wonder watches on with an understandably uneasy expression and the caption reveals the stakes. It's a wonderfully dramatic Silver Age setup, and the issue even sweetens the deal with entry details for a Giant $5,000 Prize Contest inside.
