The Flash #221

There's real dramatic tension packed into this May 1973 cover, as the Scarlet Speedster tears through a crumbling cityscape, his own super-speed shockwave toppling buildings and sending civilians scrambling for safety — with his anguished caption "Good grief! My super-speed is wiping out the city!" making it clear even the fastest man alive can be his own worst enemy. Nick Cardy's pencils and inks deliver a wonderfully kinetic image, the speed lines and urban devastation radiating outward from Flash in every direction. As a bonus, this issue also promises a Green Lantern solo backup story, "Death-Threat on Titan!" — solid value for twenty cents in 1973.
