Bio: Like Roy Rogers or Dale Evans, Buck Jones was the (stage) name of a real person. Principally an actor in western B-films, Jones was an established part of Columbia's studio system who enjoyed a loyal following. For a brief period of time in the late 1930s, he is said to have received more fan mail than any other star in Hollywood. A veteran of both World War I and World War II, he died in a massive fire at a nightclub in 1942.
Notes: While Jones did have a few comic book appearances prior to his death, he never appeared on the cover of a book until about a decade after his death. Dell's decision to turn his "Marshall Buck Jones" persona into a headliner turned out to be something of an insurance policy for his wife.
