Non-violence ou Non Violence is both a project and a sculpture created by the Swedish artist Carl Fredrik Reuterswärd following the death of John Lennon. The work depicts a revolver with a knotted barrel and exists in many versions.
There are three original copies of the sculpture, made in bronze and measuring 1.50 meters high. The first is in front of Malmö station (Bager Place, installed in 1985). The second was offered in 1988 by the government of Luxembourg at the headquarters of the United Nations in New York. A third is located at the headquarters of the European Commission, in the Kirchberg district of Luxembourg, opposite the Jean Monnet building [wiki]
