The Flash #105

The cover of this March 1959 DC issue pulls you straight into a hall-of-mirrors trap, where the Scarlet Speedster lunges forward only to face a row of identical green-and-gold villains — each one armed and taunting, "No use, Flash — you'll never find the real me in time!" Carmine Infantino and Joe Giella's cover art captures the disorienting menace beautifully, with the Flash's speed lines contrasting against the still, smirking duplicates surrounding him. Billed as "Master of Mirrors," this one promises a cerebral challenge to match any physical one for the Fastest Man Alive.
