Portrait of a gentleman of the Marenzi house Vittore Giuseppe Ghislandi (1655-1743)

The picture has something of this: people, portrait, man, wear, royalty, costume, queen, music, jewelry, monarch, lid, facial hair, crown, veil, mustache.
Perhaps it’s a painting of a man with long blonde hair wearing a black suit and gold trimmings and holding a white glove in front of his left hand.
