Was it the Fall of Communism, or just Fall 1989? Vol 2 No 4

In summer of 1989, the world watched the Chinese Communist government order its soldiers to open fire on demonstrating students; Skid Row's "18 and Life" took on new meaning, and Winds of Change were blowing on a new Paving Stone Industry Association.
