Issued by the Deutsche Demokratische Republik (DDR) in 1964, this 5-pfennig stamp commemorates the decision of the Socialist Unity Party (SED) at its 5th Congress to construct an FDGB holiday cruise ship. The design by Priess features a detailed profile and blueprint of the planned vessel, symbolizing socialist progress and worker recreation. A red party flag with the inscription “V. Parteitag der SED” and a raised fist emphasizes political commitment to social welfare. A fine thematic piece for collectors of maritime, political history, or East German issues.
