Detective Comics #302

This April 1962 issue of Detective Comics delivers one of the more imaginatively unsettling threats the Dynamic Duo has faced, with cover art by Sheldon Moldoff showing Batman and Robin caught in a beam fired from a mysterious handheld device, their bodies already turning bronze as they're transformed into statues. Bursting through a skylight above them, Batwoman arrives just a moment too late, her speech bubble crying out in alarm at the scene unfolding below. It's a wonderfully dramatic Silver Age cover that captures both the outlandish peril and the breathless pacing that made DC's early-'60s output so entertaining.
