All-American Comics #95

This 1948 DC gem spotlights the drama of "The Unmasking of the Harlequin!" right on its cover, where Green Lantern lifts his mask with a knowing smirk while the colorfully costumed Harlequin — complete with jester's collar, striped leggings, and a mallet slung over her shoulder — holds her own mask up in a moment charged with mutual revelation. Behind the two figures, a chaotic street scene plays out with police scrambling amid smoke and crowds, giving the confrontation a wonderfully theatrical backdrop. Cover art by Carmine Infantino makes this 52-page package a vivid snapshot of late Golden Age storytelling at its most playful.
