Frans (I) Hals (1582/83-1666) – Portrait of a Man Kobenhavn (SMK) National Gallery of Denmark

The picture has something of this: people, portrait, man, mustache, wear, facial hair, elderly, music, leader, jacket, lid, side view, writer, indoors, authority.
Perhaps it’s a painting of a man in a black outfit with a white collar and a ring on his left hand and his right hand in his other hand.
