This is a German Rail weekend ticket purchased at Ostbahnhof during a short stay in Berlin in 1998. About nine years after the reunification of East and West Germany, redevelopment projects were underway all over the city. I remember people saying, "The physical wall has been removed, but the wall between East and West still exists in our minds." It's a paper ticket, denominated in Deutsche Marks, and it quietly conveys the atmosphere of Berlin after reunification.
