Detective Comics #238

Here's a December 1956 issue that puts the reader right in Batman and Robin's shoes — literally. Sheldon Moldoff's cover presents the Dynamic Duo standing before three mysterious doors, each bearing a chilling label: one promises death, one escape, and one freedom, while the story title "The Doors That Hid Disaster" dares you to guess which is which. It's a wonderfully tense puzzle-box setup that captures the era's knack for drawing readers in with a single irresistible question.
