The Son of Man
One of Magritte's most common artistic devices was the use of objects to hide what lies behind them. For example, in "The Son of Man" (1964) an apple hides the face of a man wearing a bowler hat, and in "The Pleasure Principle" (1937) a bright flash likewise obscures a face. In "The Human Condition", the cover-up appears in the form of a painting within a painting.
