On Tuesday I got four postcards: one from Poland, one from Hong Kong, one from Vietnam and one from Germany.
The card from Poland shows the Maritime Museum in Szczecin. The Maritime Museum is housed in the former building of the city museum, that was finished in 1913 when Szczecin was still a part of Germany. After World War II Szczecin became a part of Poland, the city museum moved to another place and the Maritime Museum was set up in the building. Since 1970 it is part of the National Museum in Szczecin.
With a nice stamp:
