Portrait of the navigator Yu.F. Lisyansky Vladimir Borovikovsky (1757-1825)

The picture has something of this: portrait, people, wear, man, jacket, vintage, retro, lid, music, pants, mustache, outerwear, facial expression, military uniform, exploration, military.
Perhaps it’s a painting of a man in a uniform sitting at a table with a knife and fork in his hand and writing on a piece of paper in front of paper.
