Portrait of Count Carlo Marenzi Piccio (Giovanni Carnovali) (1804-1873)

The picture has something of this: people, portrait, man, lid, mustache, leader, veil, pope, cap, facial hair, beard, wear, side view, politician, profile.
Perhaps it’s a close up of a painting of a man wearing a blue hat and a black jacket with a white shirt and a green tie and white shirt.
