We asked artist Luc Tuymans to help us. He is Belgium’s most famous painter and probably one the most important painters alive. His works are shown in museums all over the world such as the MOMA in New York. His paintings trade at very high prices. (One of his paintings was sold at Christies for 1.4 million US dollars.)Luc Tuymans secretly painted on a wall in a city center. For 48 hours, hidden cameras recorded the reactions of the passers. Would they notice this valuable painting? Does our society have an eye for art?
