In November 1989, East Berliners pour over the border in their Trabants, or Trabis as they are affectionately known. West Berlin has never seen anything like it.
Every GDR citizen gets 100 Deutsche marks as a welcome gift. After queuing up at the bank, the new arrivals take their money and crowd into shopping centres around West Berlin.
Some West Berliners are quick to complain about the shops being so full, but most people are very understanding.
