Jeffrey Catherine Jones was an American artist whose work is best known from the late 1960s through the 2000s. Jones provided more than 150 covers for many different types of books through 1976, as well as venturing into fine art during and after this time. Fantasy artist Frank Frazetta called Jones "the greatest living painter". Although Jones first achieved fame as simply Jeff Jones and lived for a time as a male, she later changed her name and was legally recognized as female.
