Borch, Gerard ter (II) – De beëdiging van het vredesverdrag tussen Spanje en de Verenigde Nederlanden in het Raadhuis van Munster, 15 mei 1648, 1648-1670 Rijksmuseum: part 1

The picture has something of this: people, many, group, woman, man, wear, room, leader, indoors, seat, child, furniture, education, ceremony.
Perhaps it’s a painting of a group of men and women standing in front of a table in a room with a chandelier and a flag hanging from the ceiling.
