"The Pleasure Principle (Portrait of Edward James)" in 1937 by René Magritte (Lessines 1898 - Bruselas 1967). Oil on canvas in surrealist style. While working on the portrait of Edward James after a photograph by Man Ray. Magritte substituted the explosion of light produced by a camera flash device for the face of his model, thereby - as so often - mocking and demonstrating the principle of unreality lying behind a picture.
