Perroneau Jean-Baptiste (1715 Paris – 1783 Amsterdam) – Theophile van Robe (74x57 cm) 1770 J. Paul Getty Museum

The picture has something of this: people, portrait, man, jacket, wear, outerwear, music, musician, leader, elderly, cravat, facial expression, lid, neckwear, confidence.
Perhaps it’s a close up of a painting of a man with white hair and a gray suit with a gold trim around his neck and hands on a chair.
