9. Banksy's Installation
Not so much forgery as it is installation art - the well-known street artist Banksy went around to the world's best museums (Metropolitan Museum of Art, MoMA, American Museum of Natural History, Brooklyn Museum, The Louvre) and mounted his own art onto empty walls alongside the real stuff. For some museums, it took only hours to notice the change - for others, months. When asked what his motivations were, Banksy responded, "I thought some of the paintings were quite good. That's why I thought, you know, put them in a gallery. Otherwise, they would just sit at home and no one else would see them." Excellent point.
