The picture has something of this: horse, cavalry, mare, mammal, equine, pasture, stallion, equestrian, racehorse, mane, farm, livestock, chestnut, pony, mustang, seated, two, animal, foal.
Perhaps it’s a painting of a horse in a stable with hay on the ground and a person holding a horse’s bridle in the foreground.
