75th Anniversary of the Universal Postal Union - 10 buqsha

This stamp commemorates the 75th anniversary of the Universal Postal Union (1874–1949), a significant program celebrating the standardization of international postal networks and communications. The central illustration features the portrait of Imam Ahmad bin Yahya, who succeeded his father in 1948, anchoring the stamp in the political and institutional timeline of the Mutawakkilite Kingdom of Yemen. Flanking the portrait are two contrasting vignettes that convey a powerful message of transition: on the left, a traditional post-rider on horseback represents the kingdom's historical mail routes, while on the right, a modern propeller airplane symbolizes the adoption of fast airmail services. By participating in this global anniversary, Yemen proudly highlighted its connection to international infrastructure and global standards, using the 4-bogshas denomination to frame its unique Zaydi leadership as a forward-looking protector of national heritage and bureaucratic progress.
