Portrait of Prince Nikolai Grigoryevich Repnin-Volkonsky Vladimir Borovikovsky (1757-1825)

The picture has something of this: people, portrait, man, wear, exploration, retro, astronaut, sword, helmet, knight, book bindings, hero, armor.
Perhaps it’s a close up of a painting of a man in a uniform with a dog on his lap and a hat on his shoulder and a teddy bear in his lap.
