Francois Magendie (1783-1855) Paulin Jean Baptiste Guerin (1783-1855)

The picture has something of this: portrait, people, man, wear, neckwear, cravat, model, writer, jacket, scarf, outerwear, poetry, woman, leader, menswear.
Perhaps it’s a close up of a painting of a person wearing a black coat and a white shirt with a white collar and a red stripe around the neck.
