Mondo Cane: Yves Klein. Anthropometries of the Blue Period

Wikipedia: "He (Klein) suffered a first heart attack whilst watching the film Mondo Cane (in which he is featured) at the Cannes Film Festival on 11 May 1962. Two more heart attacks followed, the second of which killed him on 6 June 1962. His son, Yves, was born a few months later in Nice."

Encyclopedia Britannica: "Klein died at age 34, but the variety of work he produced in his brief life and his many manifestos made him one of the groundbreaking artists of the 20th century."

Guggenheim Museum: "Klein died suddenly on June 6, 1962, in Paris."
