Batman #167

Batman #167 brings a full book-length spy-thriller to DC's 1964 lineup, promising wall-to-wall tension with its cover-bannered story "Zero Hour for Earth!" Cover artists Carmine Infantino and Murphy Anderson set a striking scene: Batman and Robin are caught in twin beams of blinding light from an unseen source, recoiling against a rugged outdoor backdrop while a masked, shadowy figure looms large between the title letters above them. It's a wonderfully tense image that captures the Dynamic Duo at a genuine disadvantage — exactly the kind of cover that made Silver Age Batman irresistible.
