Begegnung Russischer Ulanen Und Dragoner Karl Friedrich Schulz (1796-1866)

The picture has something of this: mammal, cavalry, people, seated, group, man, camel, herder, military, equestrian, many, transportation system, wear, livestock, weapon, desert, competition, group together.
Perhaps it’s a painting of a group of men riding on the backs of horses in a field with a flag in the foreground and a house in the background.
