Portrait of the artist J. F. Yanenko in armor. 1841 Karl Pavlovich Bryullov (1799-1852)

The picture has something of this: portrait, people, man, jacket, wear, mustache, exploration, necklace, facial hair, lid, retro, coat, scientist, goatee, writer, leader.
Perhaps it’s a close up of a painting of a man wearing a black suit and holding his hand on his chin and looking at the camera with a serious look on his face.
