Landscape with Figures by a River. (1953-54) Camille Pissarro (1830-1903)

The picture has something of this: people, landscape, outdoors, group, water, mountain, nature, tree, rock, recreation, geology, scenic, river, man.
Perhaps it’s a painting of a group of people riding horses next to a river with a man on a horse and a dog on the other side of the river.
