Action Comics #406

Action Comics #406 (November 1971) serves up a genuinely eerie premise right on the cover: Superman — in full costume — lunges forward through what appears to be a shadowy stone corridor, while a startled man holding a lantern insists he's looking at "the Ghost of Superman." The speech bubbles crackle with disbelief as Superman fires back that ghosts don't exist and he's very much alive, setting up the lead story "Master of Miracles!" with real intrigue. Curt Swan and Murphy Anderson bring their polished, expressive line work to the cover, and at 48 pages for just 25 cents, this issue also promises a bonus team-up of the Atom and the Flash — solid value for any fan of the era.
