The Phantom Stranger #28

That cover by Nick Cardy says everything you need to know about the unsettling mood DC's mystery line delivered in January 1973 — a wild-eyed, sweating figure recoils in pure horror at a framed portrait whose face has twisted into something grotesque and barely human. The dissonance between the ordinary picture frame and the monstrous visage within makes for one of the more quietly disturbing images of the era. Inside, Arnold Drake scripts "The Counterfeit Madman!" with art by Gerry Talaoc, and the book doubles down on the weird with a bonus Spawn of Frankenstein tale as well.
