Batman #276

Batman swoops through a moody, rain-soaked Gotham night on this June 1976 cover, his cape spread wide as he pursues a billowing, spectral green figure — the villain known as the Spook — whose tattered robes trail across the city skyline in genuinely unsettling fashion. Ernie Chan's cover art delivers a wonderfully atmospheric chill, balancing superhero action with something closer to a ghost story. "The Haunting of the Spook!" promises exactly the kind of eerie, pulpy thriller that made mid-'70s Batman such a treat.
