Superman #150

From January 1962, Superman #150 features a cover by Curt Swan and George Klein that perfectly captures the story's tantalizing premise: Superman plunges headfirst toward a Metropolis street, pleading with onlookers to recognize him — while the crowd below, including police officers, stares up in bafflement, insisting they've never heard of him. The featured story is titled "When the World Forgot Superman!", and that cover image of the Man of Steel desperately trying to prove his identity to a disbelieving city speaks volumes about the imaginative storytelling inside from writer Jerry Siegel and artist Al Plastino. A wonderfully offbeat slice of early-'60s DC storytelling that captures an era when Superman's adventures could be gloriously strange.
