Sheikh Shakhbut - 15 naye paise

This stamp is a foundational value from the historic 1964 first definitive series issued by the Emirate of Abu Dhabi (أبوظبي), printed by the British security firm Harrison & Sons Ltd. The vertical composition features an elegant, octagonally framed portrait of Sheikh Shakhbut bin Sultan Al Nahyan, who ruled Abu Dhabi from 1928 to 1966. This series marked a major evolutionary step for the emirate's independent civil administration, replacing the previous reliance on British Agency overprints with a natively branded postal infrastructure.
