Issued in 1957, this striking Finnish stamp commemorates the 50th anniversary of the Central Organization of Finnish Trade Unions (SAK), founded in 1907. The bold red design depicts a series of strong, upraised arms gripping a hammer — a dynamic symbol of labor and solidarity — alongside a laurel branch signifying honor and achievement. The bilingual inscription “TYÖN KUNNIAKSI – TILL ARBETETS ÄRA” translates to “To the Glory of Work,” reflecting Finland’s deep respect for workers’ contributions during a century of industrial and social progress. A powerful and iconic issue in Finnish labor-themed philately.
