This is a 20 para red stamp from the Ottoman Empire, issued during the late 19th to early 20th century (typically between 1892 and 1908). The intricate arabesque frame and calligraphic tughra (the Sultan’s imperial monogram) are characteristic features of Ottoman postal design, symbolizing royal authority. The script in Arabic Ottoman Turkish denotes “Posta” (Post) and the denomination. The postmark in black adds historical authenticity, reflecting real postal circulation during the final decades of the empire.
