Maria Arnold initially worked at a topless bar in the San Fernando Valley as a bikini waitress who not only sold beer, told jokes, and played the harmonica, but also averaged $250 dollars per week. After quitting said job, Arnold began her career in the adult entertainment industry as a nude model. Maria appeared in her first softcore movie in the late 1960s and made the leap into hardcore porn in the early 1970s. Arnold went on to work profusely in both adult fare and exploitation features alike for about a decade before eventually calling it a day as an actress in the late 1970s. She is the daughter of Phil Arnold.
