House of Mystery #2

In "The Mark of X," uranium prospector Clyde is haunted not by death, but by the cruel illusion of it—tricked into believing he's a ghost, drifting through the wilderness he once called home. With his criminal partner Steve exploiting his fear, the line between reality and madness begins to blur. Written by an unknown hand and illustrated with haunting clarity by Curt Swan, with inks by Sy Barry, this 1952 tale from House of Mystery delivers a chilling psychological twist. The cover, penciled by Swan and inked by Ed Smalle, captures the eerie stillness of a man lost to his own mind.
