Introduction of transit visas
In 1968 West Berliners travel on holiday by long-distance coach. But this method of transport is not without its drawbacks: in mid-June 1968 the GDR introduces a mandatory passport and visa fee for transit traffic between Berlin (West) and the Federal Republic. The charge of five West German marks per person will give a significant boost to the GDR's foreign currency reserves.
