Yves KLEIN :: FC 1 (Fire-Color 1) . [1962] - http://www.businessweek.com/news...
"This 10-foot-wide artwork involved two naked models, a blowtorch and a fireman. “It’s really his masterpiece in the proper sense of the word,” said Loic Gouzer, the specialist in postwar and contemporary art. “He was risking his life.” Klein sprayed the models with water as they press their naked bodies against specially treated cardboard panels. Once the models move aside, Klein grabs the blowtorch and directs the flame at the surface. The steps are repeated as the models coat themselves with paint, leaving the marks of their breasts and thighs. While the artist directed the models and adjusted their positions, he never actually touched the surface with his hand." - Adriano
