Glossy 8×10 black and white chest-up costume portrait from The Magic Carpet (1951), boldly signed in later years in black felt tip ink, “God Bless/John Agar.”  Very fine condition.  John Agar got bitten by the acting bug following his marriage to Shirley Temple in 1945, and established a steady five-decade career — if only of rather modest artistic merit — in films and television, frequently in “B” montster movies such as Revenge of the Creature, Tarantula (both 1955), and The Mole People (1956).
