Schreyer Adolf Arab Warrior Leading A Charge Adolf Schreyer (1828-1899)

The picture has something of this: cavalry, mammal, people, fun, animal, outdoors, man, nature, dog, bird, motion, two, woman, grass, poultry.
Perhaps it’s a painting of a man riding on the back of a white horse in a field with tall grass and a body of water in the back ground.
