Portrait of Nicholas Pierre Tiolier c1817 Francois-Edouard Picot

The picture has something of this: people, wear, man, portrait, facial expression, seat, outfit, pants, jacket, retro, two, woman, outdoors, outerwear, lid.
Perhaps it’s a painting of a man in a blue jacket and brown pants, leaning on a tree trunk, with a book in his hand, in a wooded area with a castle in the background.
