Portrait of Robert Louis Stevenson (1850-1894) Sir William Blake Richmond (1842-1921)

The picture has something of this: people, portrait, man, wear, blood, woman, jacket, outerwear, face, brunette, fashion, ghost, costume, coat, zombie.
Perhaps it’s a painting of a man with long hair and a moustache on his face, sitting in a chair with a red wall in the background.
