The Flash #108

From September 1959, this issue of DC's The Flash presents a genuinely unsettling predicament right on the cover: the Scarlet Speedster races at a staggering 80,000 miles per hour on a treadmill, desperately pleading with a white-coated scientist to blast him with radiation — not to go faster, but to slow him down before it's too late. The striking purple background and Carmine Infantino's clean, kinetic linework (inked by Joe Giella) make the scene feel both urgent and wonderfully strange. Featuring the story "The Speed of Doom!", this is Silver Age DC storytelling at its most inventive — proving that sometimes the greatest threat to the Fastest Man Alive is his own incredible speed.
