Flying Childers James Seymour (1702-1752)

The picture has something of this: cavalry, seated, mammal, people, horse, man, sunset, recreation, two, wear, silhouette, equestrian, transportation system, motion, hurry, competition.
Perhaps it’s a painting of a man riding on the back of a brown horse with a white stripe down the side of the horse’s body and a sky with clouds in the background.
