After the bath Hans Olaf Heyerdahl (1857-1913)

The picture has something of this: water, swimming, wet, people, leisure, man, swimming pool, recreation, relaxation, dug-out pool, sea, beach, swimmer, seashore, shirtless, vacation, resort, lifestyle.
Perhaps it’s a painting of a boy sitting on a rock next to a body of water with a sailboat in the distance.
