Dutch expo reveals surprising side of masterpieces

For centuries many have pondered what lies behind the Mona Lisa's enigmatic smile, but it was more of a rhetorical question. Now art lovers can literally discover what the back of Da Vinci's masterpiece looks like.

In a unique and quirky Dutch exhibition, Brazilian artist Vik Muniz displays about 15 painstakingly recreated exact reproductions of the backs of some of the world's most famous paintings.

There's Vincent van Gogh's Starry Night leaning facing the wall across the room from Vermeer's The Girl with a Pearl Earring. A massive, almost bare, wooden frame is the stark reverse side of Rembrandt's haunting The Anatomy Lesson of Dr Nicolaes Tulp.
