Rousseau,H. Landscape-Park with Kiosk, 1902-03, Barnes found Henri Julien Felix Rousseau (1844-1910)

The picture has something of this: landscape, tree, outdoors, daylight, people, grass, agriculture, recreation, flower, cropland, golf, leisure, sky, farm, military, home, summer.
Perhaps it’s a painting of a group of people on a path in a field with a tent in the background and a dog on the other side of the path.
