Portrait of Adjutant General Count Peter Alexandrovich Tolstoy Vladimir Borovikovsky (1757-1825)

The picture has something of this: people, portrait, man, wear, leader, administration, royalty, music, musician, jacket, outerwear, medal, facial expression, politician.
Perhaps it’s a close up of a painting of a man wearing a blue uniform with a red sash around his neck and a medal.
