Sten Bielke (1624-1684) * David Klöcker Ehrenstråhl (1629-1698)

The picture has something of this: people, portrait, leader, famous, man, elderly, person, wear, scientist, facial hair, engraving, writer, jacket.
Perhaps it’s a close up of a painting of a man in a red coat with a fur collar and a moustache on his left side of his face.
