Marcel Broodthaers's "La pipe (this is not a pipe)" is a conceptual work that engages with René Magritte's famous 1929 painting "The Son of Man" by appropriating and recontextualizing the image of a pipe. Through this appropriation, Broodthaers explores the relationship between representation and reality, questioning how meaning is constructed in art and the act of artistic authorship itself. The work exemplifies Broodthaers's broader practice of using appropriation and institutional critique to challenge conventional modes of artistic production and exhibition.
