The largest art installation made entirely from coat hangers is Silver Back by David Mach (UK), who created a 2.1-m (7-ft) tall, 2.7-m (9-ft) long, 1.5-m (5-ft) wide sculpture of a male gorilla out of 7,500 metal coat hangers. Silver Back took 2,705.6 man-hours to create and first went on display at the FIAC art fair in Paris, France in late October 2007.
Silver Back is one of an edition of three (two further ones planned) and the first was bought by a private collector. Mach has built many coat hanger sculptures, see website: www.davidmach.com.
