IN WHAT was billed as a month-long residency in New York City, British street artist Banksy worked at night putting stencils on walls around the city. In the morning, he posted images online that sent fans hunting to find them before they were painted over.
Last week, two of Banksy's pieces caught the eye of collectors, fetching six figures at Bonhams postwar and contemporary art sale in London.
A 27-foot Special Weapons and Tactics (Swat) van covered in his stencils sold for about US$283,500. One of his canvases of a leopard emerging from a bar code sold for more than US$206,000, exceeding presale estimates. That piece last sold at auction in 2012 for US$98,167.
