Rider in Turkish costume. Arabian breed Nikolay Sverchkov (1817-1898)

The picture has something of this: cavalry, mammal, seated, people, horse, wear, equestrian, two, man, woman, herder, recreation, motion, veil, competition, racehorse.
Perhaps it’s a painting of a man riding on the back of a white horse wearing a red uniform and a red beret, with mountains in the background.
