Martin Drolling – Painting and Music (Portrait of the Artist′s Son) Los Angeles County Museum of Art (LACMA)

The picture has something of this: people, child, two, woman, family, wear, furniture, room, sit, son, indoors, offspring, baby, man, portrait, three, group.
Perhaps it’s a painting of a young girl sitting in a window sill with a violin in her hand and a boy in the background looking out of the window.
