L.H.O.O.Q.

Image Source

No. 21 of a limited edition of 35 copies of L.H.O.O.Q. sold recently at Christie's in New York for $452,000, roughly five times as much as the auction house expected. The image -- hand-doodled by the artist on an existing mass-market reproduction -- comes from the collection of Robert Shapazian, while the auction itself has raised eyebrows (if not mustaches) from as far away as Moscow.
