Johan Kasimir (1589-1652), Count Palatine of Zweibrücken * David Beck

The picture has something of this: people, portrait, man, lid, mustache, beard, facial hair, jacket, cap, wear, veil, coat, elderly, goatee, scientist.
Perhaps it’s a close up of a painting of a man with a long white beard and wearing a black coat with a white collar and a white ruff.
