Not a self portrait of van Hoesen, the artist herself, but perhaps of her husband, artist Mark Adams? There does seem to be some resemblance (see his Curiator profile). "A young man wearing a checkered jacket, sitting with his arms and legs crossed, in front of a piano and a portrait of the same young man, with others pictures on the wall depicting small dog, a rose and grapes." http://art.famsf.org/beth-van-hoesen/artist-and-self-portrait-19841291
