This 1976 Polish issue honors two national heroes who also fought for American independence — Kazimierz Pułaski and Tadeusz Kościuszko. Each 8.40 zł stamp features their statues located in the United States: Pułaski’s monument in Buffalo, and Kościuszko’s in Philadelphia. The designs, in strong violet and brown backgrounds, emphasize bronze textures and heroic posture. Both men symbolize Poland’s enduring ties with the U.S. and shared ideals of liberty. A meaningful set for collectors of Polish-American heritage or historical figures themes.
