The vessel was put into service in Sweden 1925 under the name of "Gripsholm".It was the first North-Atlantic -Liner driven by Diesel- engines. During the war Sweden gave the "Gripsholm" to the International Committee of the Red Cross for humanitarian services. After the war it served on the Göteborg-New York line. Modernized in 1949/50 it was sold in 1955 to the "Norddeutsche Lloyd" shipping company and renamed to "Berlin". The Berlin ran on the Bremerhaven-New York line. However the ship was to slow to be competitive with modern liners. It was then used for cruises. In 1966 the ship was put out of service and scrapped. Stamps issued March 12th,1955. p.s.: If I am not completely wrong these stamps are the only ones of (West-) Berlin,inscribed "Landespost Berlin". Earliar ones were inscribed "Deutsche Post" or "Deutsche Post Berlin", later ones "Deutsche Bundespost Berlin".
