Superman #220

Something has clearly gone wrong in the DC Universe when the Flash throws a super-punch at Superman — only to watch it pass right through him, as the cover's speech bubbles make delightfully clear. Curt Swan and Murphy Anderson's cover art captures the moment perfectly: the Scarlet Speedster winds up for a haymaker while a bemused Man of Steel stands unphased against a brick wall, the story's tag line — "Who Stole My Super-Powers?" — teasing the mystery within. Written by Jim Shooter with interior art by Curt Swan and George Roussos, this 1969 issue promises a fun team-up between two of DC's heaviest hitters at fifteen cents well spent.
