Traditional Architecture with Wind Tower - 75 naye paise

This dark grey 40-naye-paise airmail issue highlights the defensive architectural heritage of the emirate's East Coast by depicting the historic Castle of Kalba (قلعة كلباء). The detailed landscape illustration captures the massive coral-stone and mud-brick bastions, tapering watchtowers, and fortified perimeter walls of the coastal fort complex, flying a traditional flag against a clear blue sky. Superimposed to the right is the collection's signature oval portrait of the sovereign ruler, Sheikh Saqr bin Sultan Al Qasimi, providing the administrative validation for this mid-tier utility rate printed by Harrison and Sons Ltd. London to handle international postal traffic.
