Rembrandt, Harmenszoon van Rijn – Portrait of an old Jew Hermitage ~ part 10

The picture has something of this: people, portrait, veil, museum, Renaissance, ancient, facial hair, wear, facial expression, mammal, baroque, mustache, bird.
Perhaps it’s a close up of a painting of a man with a long beard wearing a black hat and a brown coat and holding a piece of paper in his hand.
