Fredrik Axel von Fersen (1719-1794), Count Gustaf Lundberg (1695-1786)

The picture has something of this: portrait, people, jacket, wear, outerwear, man, sword, necklace, woman, royalty, facial hair, coat, writer, facial expression, Renaissance, retro.
Perhaps it’s a close up of a painting of a man in a blue coat with a feather on his lapel and a feathered hat on his head.
