Portrait of Bronze Otto Eerelman

The picture has something of this: horse, cavalry, mare, farm, animal, stallion, mammal, equine, racehorse, grass, equestrian, field, pasture, nature, mane, rural, seated, agriculture, thoroughbred.
Perhaps it’s a painting of a black horse with a saddle on it’s back standing in a grassy field with a white fence and blue sky in the background.
