This painting is called The Rebel (Elizabeth Ruskin) and was painted by Lew Davis (1910-1979).
Davis was born in Jerome Arizona but left Arizona when he was 17 to study art in New York City. He became adept at painting human figures and often depicted women laboring in oppressive conditions.
The Phoenix Art Museum describes the painting this way:
"This painting features one of his fellow students, Elizabeth Ruskin. Although she stares directly at the viewer with an unsettling intensity, we know very little about her story except that she was a student in one of his classes. That she was attractied to Davis is suggested by the two apples on the plate on the floor that allude to Adam's temptation of Eve."
I love seeing this painting whenever it is on display at the museum.
