25 years Arab Postal Union - 40 fils

Issued in 1977, this stamp commemorates the 25th anniversary of the Arab Postal Union (1952–1977), an organization established to strengthen cooperation among Arab postal administrations and improve postal services throughout the Arab world. Since its founding in 1952, the Union worked to facilitate the exchange of mail, harmonize postal regulations, and promote collaboration in communications, helping to strengthen links between Arab countries.

By issuing this commemorative stamp, the State of Bahrain celebrated a quarter century of Arab postal cooperation and recognized the important role of postal services in supporting communication, commerce, and cultural exchange. The issue highlighted the value of regional collaboration and reflected the continuing efforts of Arab nations to enhance communication networks and foster closer ties through efficient and coordinated postal systems.
