Retrato de hombre Diego Rodriguez De Silva y Velazquez (1599-1660)

The picture has something of this: people, portrait, man, wear, facial expression, face, leader, side view, facial hair, outerwear, profile, mustache, lid, jacket, popularity, confidence.
Perhaps it’s a close up of a painting of a man wearing a black shirt with a white collar and a moustache on his left side of his face.
