Backer, Jacob Adriaensz. – Officieren en andere schutters van wijk V in Amsterdam onder leiding van kaptein Cornelis de Graeff en luitenant Hendrick Lauwrensz, 1642 Rijksmuseum: part 4

The picture has something of this: people, group, lid, man, woman, many, veil, wear, uniform, child, weapon, crowd, group together, military, boy, soldier, recreation, war.
Perhaps it’s a painting of a group of men standing next to each other in front of a building with a flag on the top of one of the men’s shoulders.
