Retrato de hombre, el llamado Barbero del Papa Diego Rodriguez De Silva y Velazquez (1599-1660)

The picture has something of this: people, portrait, man, mustache, elderly, leader, facial hair, scientist, writer, wear, politician, engraving, poet.
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.
