If you want someone to blame for Banksy¡¯s stunt of shredding ¡°Girl With Balloon¡± after selling it for $1.4 million at auction, your prime suspect currently has a major retrospective at the Tokyo National Museum.

Skepticism of the British graffiti artist¡¯s aesthetic value may not be cured by seeing the two-part ¡°Marcel Duchamp and Japanese Art¡± exhibition, but the show is a comprehensive exploration of how and why modern art broke away from painting and the idea of craftsmanship.

One person¡¯s terrorist is another¡¯s freedom fighter, and Duchamp¡¯s revolutionary attack, 100 years ago, on the assumptions of what constitutes art and beauty, still radically divides people.
