Superboy #20

From 1952 comes this intriguing chapter in the Boy of Steel's early adventures, featuring the story "The Ghost That Haunted Smallville!" The cover by Win Mortimer places Superboy face-to-face with a translucent, ghostly figure declaring himself to be Jor-El — Superboy's Kryptonian father — while a mysterious purple structure labeled "Station G.H.O.S.T." looms in the background and onlookers watch the startling encounter. It's a wonderfully atmospheric ten-cent package, with writer Bill Finger and artist John Sikela bringing their talents to bear on a tale that promises secrets, spectral mystery, and a hero confronting his own origins.
