Indian Seated by a Campfire Eanger Irving Couse (1866-1936)

The picture has something of this: people, reclining, nude, man, wear, shirtless, beach, kneeling, sand, facial expression, woman, seashore, son, child.
Perhaps it’s a painting of a native american man sitting in the sand with a campfire on the other side of the painting, with trees in the background.
