Jan 01, 1969 - London, England, UK - YOKO ONO und JOHN LENNON, at the an opening of Lennon's exhibit. Knowing their March 20, 1969 marriage would be a huge press event, John and Yoko decided to use the publicity to promote world peace. Lennon and Ono often combined advocacy with performance art, as in their "Bagism" introduced during a Vienna press conference. Lennon detailed this period in the Beatles' song "The Ballad of John and Yoko". (Credit Image: © Keystone Pictures/ZUMA Press) RESTRICTIONS: * Germany Rights OUT *
