Portrait of Prince P. Shcherbatov. Ok. 1808. H., M. 68h52. GRM Orest Adamovich Kiprensky (1782-1836)

The picture has something of this: portrait, people, wear, leader, woman, man, writer, wig, music, scientist, retro, elderly, outerwear, administration.
Perhaps it’s a portrait of a man with white hair wearing a black jacket and a white shirt with a red flower on his lapel and a black background.
