The picture has something of this: cavalry, battlefield, army, people, military, rider, gun, combat, soldier, reenactment, skirmish, war, man, seated, uniform, horseback, cowman, equestrian, weapon, rifle.
Perhaps it’s a painting of a group of men riding horses in a field with an american flag on top of one of the horses and another man holding a flag.
