Banksy's half-shredded artwork is on sale again — and it may fetch millions more this time

A Banksy artwork that sensationally self-shredded just after it sold for $1.4 million is up for sale again — at several times the previous price. 

Auctioneer Sotheby's said Friday that "Love is in the Bin" will be offered at a sale in London on Oct. 14. The piece has a pre-sale estimate of 4 million to 6 million pounds ($5.5 million to $8.3 million). It consists of a half-shredded canvas bearing a spray-painted image of a girl reaching for a heart-shaped red balloon.
