Bastiaan de Poorter – Portrait of Jean Zacharia Mazel (1792-1884) Mauritshuis

The picture has something of this: people, portrait, administration, leader, man, chair, outfit, wear, side view, furniture, business, music, room, politician, seat, military, facial expression, offense.
Perhaps it’s a painting of a man in a black suit and white shirt sitting in a chair with his hand in his pocket and his right.
