The Sergeants Portrait 1874 73x62cm Jean-Louis Ernest Meissonier (1815-1891)

The picture has something of this: people, weapon, military, soldier, man, cavalry, group, street, costume, war, festival, gun, rifle, wear, uniform, army, woman, battle, music.
Perhaps it’s a painting of a group of men standing in front of a brick building with one man holding a gun and another man with a dog.
