Issac Adolphe Bouguereau Adolphe William Bouguereau (1825-1905)

The picture has something of this: people, man, portrait, facial hair, leader, person, mustache, pensive, wear, profile, collar, head, face, beard, engraving.
Perhaps it’s a painting of a man in a tuxedo with a beard and a bow tie in a round frame with a damask wall in the background.
