This 1985 commemorative stamp from Poland marks the 40th anniversary of the Recovered Territories (Ziem Odzyskanych) and honors Piotr Zaremba, the first post-war president of Szczecin (1945–1950). The design features Zaremba’s portrait alongside a stylized map highlighting key cities such as Szczecin, Wrocław, Gdańsk, and Olsztyn, symbolizing post-war reconstruction and regional integration. Issued in a 20 zł denomination, the stamp reflects an important chapter in Poland’s administrative and urban rebuilding history. Its historical theme, map-based artwork, and political commemoration make it a notable addition to collections focused on European post-war issues, political figures, or regional development themes.
