Portrait of an unknown with a commanding cross of the Order of St. John of Jerusalem Vladimir Borovikovsky (1757-1825)

The picture has something of this: people, portrait, wear, man, leader, music, writer, outerwear, jacket, scientist, side view, retro, administration, facial hair, elderly.
Perhaps it’s a close up of a painting of a man in a black suit with a white shirt and a white tie and a black jacket with a tree in the background.
