This classic 1 Kuruş definitive stamp features a finely engraved portrait of Mustafa Kemal Atatürk, founder and first President of modern Turkey. Issued as part of the long-running republican definitive series, the stamp reflects Turkey’s early nation-building period and postal modernization. The clean typographic design with “POSTALARI” inscription represents mid-20th-century Turkish postal aesthetics. Widely used for everyday correspondence, well-preserved examples with sharp perforations and strong color are appreciated by collectors of political leaders and European definitives.
