Carl Erik Wadenstierna (1723-1807) Niclas Lafrensen (1737-1807)

The picture has something of this: people, man, picture frame, gold, portrait, metallic, margin, reflection, vintage, facial hair, soldier, lid, elderly, leader.
Perhaps it’s a portrait of a man wearing a blue coat and holding a book in his right hand and sitting in a chair in front of a gold frame.
