Action Comics #411

There's something wonderfully unsettling about a cover where Superman himself is turned away from his own Fortress of Solitude — and that's exactly the premise Nick Cardy delivers here, with the Man of Steel hovering in bewilderment before the massive golden door of his Arctic sanctuary, now plastered with "Superman — Keep Out" and "Private Property" signs while strangers wander the icy grounds below. This April 1972 issue packs an impressive 52 pages of value, leading with "The Day They Sold Superman's Fortress" and adding two more features — "The Girl Who Worshipped Clark Kent" and an Eclipso reprint asking whether he was hero or villain. It's a genuinely fun package that captures early-'70s DC at its most imaginative and jam-packed.
