Portrait of Alexander Dmitrievich Lansky Dmitry Levitsky (Levitzky) (1735-1822)

The picture has something of this: portrait, people, necklace, wear, man, engraving, royalty, jacket, leader, outerwear, facial hair, vest, vintage, writer, wig.
Perhaps it’s a close up of a painting of a person wearing a brown jacket and a white shirt with a blue tie.
