#11111 Rosa-Marie Bonheur (1822-1899)

The picture has something of this: cavalry, seated, mammal, horse, cowman, equestrian, stallion, people, two, mare, saddle, bridle, equine, farm, animal, man, horseback, mane.
Perhaps it’s a painting of a man riding on the back of a white horse on a dirt road in front of a green field and a blue sky with clouds.
