Ronald Reagan (the artist) said: "Mr. Gorbachev, overthrow this wall!". (Berlin Wall). Before this phrase, behind the scenes, there was a movement, initiated by Gorbachev that would change the communist world. Perestroika and Glasnost. Who overthrew the wall, in fact, was Gorbachev. And no, Reagan! Few people know that: the great, in history, was Mikhail Gorbachev.
