This classic Turkish definitive stamp features the historic Çankaya Atatürk Köşkü, the principal residence of Mustafa Kemal Atatürk in Ankara and a landmark of the early Republic. Printed in a rich brown monochrome tone, the design captures the villa’s elegant architecture with fine line engraving typical of mid-20th-century Turkish postal issues. Issued by the Republic of Turkey (Türkiye Cumhuriyeti Postaları), the stamp carries a 100 Kuruş denomination and was produced by Güzel Sanatlar Matbaası, Istanbul, a well-known printing house of the era. A desirable piece for collectors of Turkish history, architectural themes, and Atatürk-related philately.
