Thomas de Keyser 1596/97–1667 Amsterdam) – Portrait of a Man with a Shell Metropolitan Museum: part 4

The picture has something of this: lid, people, portrait, veil, wear, fashion, man, fedora, music, cowboy, musician, fashionable, jacket, festival, gentleman, cap, performance, model.
Perhaps it’s a painting of a man with a beard wearing a black hat and a white ruffled collar and holding a can of beer in his right hand.
