At the Dunes Hans von Bartels (1856-1913)

The picture has something of this: people, mammal, water, transportation system, vehicle, two, cart, motion, man, outdoors, recreation, cavalry, woman, carriage, daylight, group.
Perhaps it’s a painting of a man pulling a horse and buggy through a body of water with a dog on the other side of him and a stormy sky in the background.
