Cheval de Przewalski Carl Brenders

The picture has something of this: cavalry, animal, mammal, nature, wild, stallion, farm, mane, mare, rural, wildlife, livestock, horse, pasture, foal, field, equine, equestrian, grass, pony.
Perhaps it’s a painting of a brown horse grazing in a grassy field with rocks and grass in the foreground and a yellow border around the edges of the frame.
