The picture has something of this: cavalry, people, seated, equestrian, man, rider, army, military, soldier, mammal, skirmish, weapon, horseback, war, field, motion, cowman, uniform, group, flag.
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 men on the back of the horses.
