Le Macchiaiole (1865) Collezione Privata Giovanni Fattori (1825-1908)

The picture has something of this: people, weapon, military, two, gun, war, skirmish, man, wear, soldier, army, rifle, child, lithograph, woman, outdoors.
Perhaps it’s a painting of a group of people standing on top of a grass covered field next to a field with trees and a hill in the distance.
