They ride with greyhounds Sergey Vinogradov (1869-1938)

The picture has something of this: people, cavalry, veil, group, wear, mammal, herder, seated, man, many, military, woman, weapon, lid, transportation system, war.
Perhaps it’s a painting of a man riding on the back of a horse next to a group of people and a dog in front of a fenced in a field.
