The Lennon Peace Wall came about shortly after John Lennon was killed in 1980. Under communism it morphed into an impromptu protest space. The secret police tried to stop the graffiti writers, but every day the wall seemed to be covered with new messages extolling the virtues of John Lennon instead of that other "Lenin." -Frommer's
