Un Homme D-Armes Et Son Cheval Jean-Louis Ernest Meissonier (1815-1891)

The picture has something of this: people, man, cavalry, mammal, two, desert, wear, recreation, seated, outdoors, adventure, cowman, exploration, three, woman, herder.
Perhaps it’s a painting of a man leading a brown horse down a dirt road with a man in a yellow coat and hat on the side of the road.
