Anthonis Mor van Dashorst (and studio) – Portrait of a Man Mauritshuis

The picture has something of this: people, portrait, man, wear, armor, sword, veil, weapon, leader, lid, royalty, outerwear, facial hair, soldier, knight, jacket, military.
Perhaps it’s a close up of a painting of a man wearing a gold outfit with a white collar and a gold chain around his neck and a black background.
