After the Columbine High School massacre in 1999 , Ono paid for billboards to be put up in New York City and Los Angeles that bore the image of Lennon 's blood-splashed spectacles . Early in 2002 she paid about £ 150,000 ( $ 213,375 ) for a billboard in Piccadilly Circus with a line from Lennon 's " Imagine " : " Imagine all the people living life in peace . " Later the same year , she inaugurated a peace award , the LennonOno Grant for Peace , by giving $ 50,000 ( £ 31,900 ) in prize money originally to artists living " in regions of conflict " . The award is given out every two years in conjunction with the lighting of the Imagine Peace Tower , and was first given to Israeli and Palestinian artists . Its program has since expanded to include writers , such as Michael Pollan and Alice Walker , activists such as Vandana Shiva and Pussy riot , organizations such as New York 's Center for Constitutional Rights , even an entire country ( Iceland )
