Jeff Koons’s "Balloon Dog (Orange)" – a 12-foot-high, orange-tinted, stainless steel sculpture resembling a dog made from balloons – was sold at Christie’s, New York, USA, on 12 November 2013, for $58.4 m (£36.49 m), the most ever paid for a work by a living artist at auction. The sale was made to an anonymous telephone bidder, and broke the $55 m pre-sale estimate.Koons has made a career out of creating giant stainless steel balloon animals, with polished mirror surfaces, in a range of colours. "Balloon Dog (Orange)" is one of five "Balloon Dog" sculptures, created in the 1990s. The other four are coloured yellow, blue, magenta and red. His other work includes a 43-foot topiary terrier, the body paint design of a 2010 BMW Le Mans race car and the cover of Lady Gaga’s 2013 album Artpop.
