The bay of Tregastel Félix Édouard Vallotton (1865-1925)

The picture has something of this: water, outdoors, landscape, tree, bird, nature, people, seashore, reclining, dawn, beach, desert, river.
Perhaps it’s a painting of a boat on a beach next to a body of water with a rock outcropping in the distance and another boat in the water.
