La Moisson pres de la Marne Leon Augustin Lhermitte (1844-1925)

The picture has something of this: nature, landscape, tree, outdoors, wood, water, summer, environment, grass, park, scenic, mountain, countryside, wild, beautiful, sky, fair weather, rock.
Perhaps it’s a painting of a group of people working in a field with a river in the background and trees on the other side of the field, and a lake in the foreground.
