Portrait of L. Ya. Neklyudov Vasily Tropinin (1776-1857)

The picture has something of this: people, portrait, leader, wear, engraving, man, facial hair, elderly, scientist, lid, royalty, medal, monarch.
Perhaps it’s a close up of a painting of a man in a military uniform with a feathered hat on his left hand and a feathered collar on his right hand.
