To commemorate the wedding of John Lennon and Yoko Ono and their peace activities during the late 1960s, the John Lennon Museum in Japan is hosting a special exhibition until July 31 titled "John and Yoko's Love & Peace Activities 1968-1970."

A prime focus of the show will be the couple's acorn-planting project, which symbolized the growing peace movement in the late 1960s amid the horrors of the Vietnam War. The museum contains installations of acorns under glass with giant photos of an acorn-planting ceremony that Lennon and Ono had in England, during which they planted two acorns to symbolize the meeting of East and West.

A museum spokesperson displayed a photograph of a plain-colored box addressed to the president of Chile, one of the 50 boxes containing acorns sent out to world leaders during the peace campaign and "Bed-In" that followed the Lennon/Ono wedding. She explained that even though Lennon would have been 66 this year, about half of the museum visitors are in their teens and 20s.
