Cabanel, Alexander – Portrait of Prince of KA Gorchakov Hermitage ~ Part 05

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