Portrait of D. V. Kiselev Vasily Tropinin (1776-1857)

The picture has something of this: people, portrait, neckwear, popularity, wear, man, blazer, jacket, menswear, outfit, music, side view, leader, musician, outerwear, profile, administration, mustache.
Perhaps it’s a painting of a man in a black suit and white shirt sitting in a chair with a pen in his hand and a book in his other hand.
