The image on the stamp shows Taqi al-Din Muhammad ibn Ma'ruf al Shemi al-Asadi and his colleagues at the observatory of Taqf ad-Din in Istanbul in 1577 (A.H. 985). The original painting is from Shahinshah-nama (History of the King of Kings), by ’Ala ad-Din Mansur-Shirazi, in honor of Sultan Murad III.
     In the center of the foreground is a circular map. The original shows the continent of Asia, but the map on the stamp is mis-drawn.
