Flinck, Govert – Gerard Pietersz Hulft (1621-56). Eerste raad en directeur-generaal van de VOC, 1654 Rijksmuseum: part 3

The picture has something of this: people, book, helmet, portrait, church, vintage, indoors, inside, saint, Gothic, armor, war, barrel.
Perhaps it’s a close up of a painting of a man in a mirror with a lot of things on the table in front of him.
