Banksy again:
2 million pounds and up
On Friday, a Banksy painting shredded itself immediately after being sold for $1.4 million at Sotheby's in London — a prank precipitated by the artist in an apparent statement against the commercialization of art and the excesses of the art market. However, the shredded painting may be worth far more now — some 2 million pounds ($2.6 million) or more, according to a website that resells Banksy pieces. [Slate]
