Pumpkin with a Stable-lad George Stubbs

The picture has something of this: cavalry, mammal, grass, horse, mare, farm, animal, stallion, foal, hayfield, outdoors, field, pasture, equine, livestock, tree, two, sunset, sky.
Perhaps it’s a painting of a young boy standing next to a brown horse in a wooded area with a lake in the background and trees in the foreground.
