Detective Comics #346

From December 1965, this issue of Detective Comics poses a genuinely tantalizing puzzle right on its cover: a red-haired machine-gunner — boldly declared to be a world-famous celebrity in disguise — stands his ground against Batman himself, separated from the Dark Knight by panels of unbreakable jet-age plastic while deadly gas seeps up through an electrified grating below. Cover pencils by Carmine Infantino and inks by Joe Giella give the confrontation a crisp, kinetic energy that perfectly captures the era's flair for high-concept danger. With John Broome writing and Sheldon Moldoff on interior art, "Batman's Inescapable Doom-Trap!" is a wonderfully inventive slice of Silver Age suspense.
