Superman Week: Pocket Heroes (Mego; 1979)

In 1979, Mego released a series of bare-bones action figures from the Superman universe.  The sparsely decorated red cards read: "Only 3 1/4 inches tall and fully poseable. Small enough to fit into your pocket. Big enough for giant sized adventures."  

Although there are better-sculpted Pocket Heroes toys out there (from the Marvel and DC universes), these Pocket Heroes are notable for featuring the characters of Jor-El and Zod, with a loose but fair resemblance to Terence Stamp and Marlon Brando.  The Lex Luthor in this series resembles the comic-book character, rather than Gene Hackman.
