The Vintage at Chateau Lagrange Jules Adolphe Breton (1827-1906)

The picture has something of this: people, group, man, wear, mammal, veil, military, woman, weapon, lid, war, group together, soldier, herder, recreation, cavalry, transportation system, vehicle, skirmish.
Perhaps it’s a painting of a group of people in a field with a man on top of a horse and a woman on the other side of the field.
