Ballet Nils Bergslien (1853-1928)

The picture has something of this: people, military, group, woman, wear, man, soldier, war, sit, veil, grief, kneeling, position, weapon, army, pain, child.
Perhaps it’s a painting of a group of people sitting at a table in front of a building with a man holding a guitar in one hand and a woman holding a map in the other hand.
