The stainless steel capsule dedicated Friday will be kept in the Cleveland museum’s archives at a nearby college campus.

Assistant curator Meredith Rutledge tells The Plain Dealer that the goal of the capsule was to preserve the “legacy of peace and love” of the former Beatles member.

About 100 people attended the dedication, which marks the start of a weekend of events in honor of Lennon’s birthday. The capsule is scheduled to be opened in 2040, on Lennon’s 100th birthday.

Lennon was killed in 1980 outside the New York City apartment building where he lived.
