Banksy: The Unauthorised Retrospective
http://www.sothebys.com/en/auctions/2014/banksy-steve-lazarides-ls1403.html
70 works by Banksy are on view in an exhibition in Mayfair curated by Steve Lazarides. About Banksy: "I think what really made him popular was the sheer volume of stuff he put out on the street back in the day, particularly in London but around the world from Bristol to Palestine. People loved walking round the corner and seeing something that would make them smile and that is what Banksy is good at, seeing things in unexpected places that make people smile." - Steve Lazarides
