Портрет Николая II 1900 часть 2 - Russian and soviet artists Русские и советские художники

The picture has something of this: people, man, portrait, wear, soldier, military, weapon, uniform, war, military uniform, veil, army, facial hair, lid, helmet, exploration.
Perhaps it’s a painting of a man in uniform sitting at a table with a knife in his hand and a book in his other hand, in front of him.
