Anton Graff (1736 – 1813) – Self-Portrait with Eye-shade Alte und Neue Nationalgalerie (Berlin)

The picture has something of this: people, portrait, man, lid, veil, Renaissance, wear, elderly, helmet, indoors, woman, sculpture, leader.
Perhaps it’s a close up of a painting of a man in a hat and coat holding a pen and writing on a piece of paper in his left hand.
