Mary Treen was a character actress who began her career on the vaudeville stage, and from there continued on to theater and movie and tv. Her movie career began in the 1930s in many uncredited roles. As audiences continued to recognize her, she eventually was given screen credit for whichever roles she played.
Ms. Treen was seen on many tv shows during the 1960s, '70s and '80s and was always fun to watch.
I wrote to Ms. Treen, at her Newport Beach, California residence, in 1982, requesting a photo. She sent this photo, within two weeks. It's signed on the upper left, in the dark portion of the photo.
