This is Anita Parkhurst, who was just starting her career. She became known for painting "the New American Woman" for magazines like
The Saturday Evening Post. She married not long after this job and used her married name, Anita Parkhurst Willcox or Anita Willcox in daily life but continued signing illustrations as Parkhurst. She was a committed pacifist and eventually left commercial art to work as a peace activist. Of course this got her in trouble with the US government. In 1950 she and her husband formed an interracial co-op community in Connecticut as a response to the Cold War, racism, and McCarthyite harassment. An interesting woman. More at Wikipedia:
