Fazl-Allah ibn Mirza Muhammad. Portrait of Nasir al-Din Shah Hermitage ~ part 12

The picture has something of this: people, vintage, man, portrait, lid, wear, antique, retro, book bindings, paper, historic, picture frame.
Perhaps it’s a painting of a man in a military uniform sitting on a chair with a rope in his hand and a sword in his other hand, with a blue sky in the background.
