This striking Polish stamp, inscribed “Rozbudujemy Stocznię Gdańska” (“We are expanding the Gdańsk Shipyard”), highlights Poland’s postwar industrial rebuilding efforts. Issued in the early 1950s, it depicts a large ship under construction in the Gdańsk Shipyard, one of the nation’s key centers for maritime engineering. The design, rendered in rich reddish-brown tones, symbolizes progress and socialist industrial strength. Engraved by E. Konecki and designed by B. Świderska, this 15 groszy issue exemplifies the era’s emphasis on labor and reconstruction through bold architectural and mechanical imagery.
