Superman #115

From 1957 comes this delightful Silver Age gem featuring the cover story "The Three Substitute Supermen!" — and Al Plastino's cover delivers the premise with infectious energy. Three candidates in Superman costumes — one notably small in stature — are put through their paces as Superman himself watches from the foreground, scorecard in hand, tallying results for Strength, Invulnerability, and Flying. The cover's playful question — which of these three will earn the right to become the new Man of Steel? — makes this August 1957 issue a genuinely fun snapshot of the era's imaginative, anything-goes storytelling.
