Douglas Vickers John Singer Sargent (1856-1925)

The picture has something of this: people, portrait, man, leader, menswear, wear, facial hair, neckwear, administration, outfit, writer, mustache, outerwear, music, bald, jacket, side view, facial expression.
Perhaps it’s a painting of a man with a moustache and a moustache on his face, wearing a black suit with a white shirt and tie.
