Portrait Of Prince K A Gorchakov Alexandre Cabanel (1823-1889)

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