Sir Tatton Sykes Leading in the Horse ’Sir Tatton Sykes’ with William Scott Up Harry Hall (1814-1882)

The picture has something of this: cavalry, people, horse, seated, mammal, equestrian, rider, racehorse, lid, saddle, two, mare, wear, equine, jockey, competition, bridle, stallion, man.
Perhaps it’s a painting of a man on a horse being led by a man in a long black coat and top hat and a woman.
