John Lennon and Yoko Ono
Produced this famous poster. December 15, 1969, John Lennon and Yoko Ono flew to Toronto, Canada on that day, to begin the next stage of their “War is Over” Christmas peace campaign. To coincide with the launch, huge posters and billboards were erected in 12 countries proclaiming "War is over! If you want it. Happy Christmas from John & Yoko”. Here is an original poster with photos from the heartfelt campaign.
