Portrait of an Old Man in Red Rembrandt Harmenszoon Van Rijn (1606-1669)

The picture has something of this: people, portrait, man, elderly, facial hair, wear, scientist, mustache, music, leader, writer, Renaissance, side view, veil.
Perhaps it’s a painting of a man with a white beard and a red shirt sitting in a chair with his hands in his pockets and looking off to the side.
