After Bronzino – Portrait of Cosimo I de Medici, Grand Duke of Tuscany Part 1 National Gallery UK

The picture has something of this: portrait, people, man, mustache, facial hair, vintage, antique, leader, Renaissance, wear, vest, goatee, collar, cravat.
Perhaps it’s a close up of a painting of a man with a beard wearing a brown coat and a white collared shirt with a green wall in the background.
