Flying Childers with Jockey Up James Seymour (1702-1752)

The picture has something of this: cavalry, horse, mammal, seated, equestrian, action energy, motion, equine, competition, fast, mare, stallion, hurry, pony, animal, two, racehorse, saddle.
Perhaps it’s a painting of a man riding on the back of a brown horse in a field with a blue sky in the background and clouds.
