Batoni, Pompeo – Portrait of Prince B. Kurakina Hermitage ~ Part 01

The picture has something of this: portrait, people, man, Renaissance, wear, royalty, leader, facial hair, jacket, mustache, monarch, engraving, saint, coat.
Perhaps it’s a close up of a painting of a person wearing a brown coat and a white shirt with a flower on it’s lapel and a black background.
