’Margrave’ with James Robinson Up John Frederick Herring (1795-1865)

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