Veytsh, Georg Friedrich – Portrait of Nikolai Mikhailovich Kamensky Hermitage ~ part 02

The picture has something of this: people, wear, woman, portrait, veil, music, girl, musician, facial expression, light, underwater, man, performance, recreation, lid.
Perhaps it’s a close up of a painting of a man in a black coat with a red collar and a chain around his neck and a tree in the background.
