Portrait of Prince Ivan Gagarin 1811 H., M. 80h69 RM Orest Adamovich Kiprensky (1782-1836)

The picture has something of this: people, portrait, man, outerwear, wear, woman, coat, jacket, facial expression, musician, music, writer, face, profile, lid.
Perhaps it’s a close up of a painting of a man wearing a black coat and a green coat with a white collar and a black fur coat over his left shoulder.
