Vigee-Lebrun, Elisabeth-Louise – Portrait of Count Grigory Ivanovich Chernyshev with a mask in hand Hermitage ~ part 03

The picture has something of this: people, portrait, wear, music, man, facial expression, musician, jacket, singer, woman, actor, boy, writer, girl, outerwear, model, indoors, confidence.
Perhaps it’s a painting of a man holding a camera in his right hand and wearing a black jacket with a red collar and white shirt on his left arm.
