Lower Oder Valley National Park is a shared German-Polish nature reserve. Its comprises the western banks of the Oder river within the Ukcermark district in the German state of Brandenburg as well as the steep eastern banks in the Gryfino and Police counties of the Polish West Pomeranian Voivodeship further north. This postcard with special stamps and postmark was sent by my best correspondent friend Erhard Molbitz from Postdam, Germany.
