Theodor Korner, Karl Friesen and Christian Ferdinand Hartmann on Outpost Duty Georg Friedrich Kersting (1785-1847)

The picture has something of this: people, lid, man, veil, wear, two, weapon, walking stick, recreation, gun, cap, group, portrait, child, rifle, woman, three, military.
Perhaps it’s a painting of a group of people in a forest, one of the men is holding a gun and the other is looking at something in the distance.
