Francis Alexander – Ralph Wheelock’s Farm National Gallery of Art (Washington)

The picture has something of this: daylight, agriculture, landscape, cropland, farm, vehicle, people, outdoors, mammal, grassland, war, pastoral, military, grass, sky, group, home.
Perhaps it’s a painting of a group of people playing a game of frisbee in a green field with a white house in the background and a row of trees in the foreground.
