This 50 halala commemorative stamp was issued by Saudi Arabia in 1987 (Hijri 1407) to mark the “Saudi Arabia: Between Yesterday and Today” exhibition held in Cairo, Egypt. The design features a symbolic blend of landmarks — the Great Pyramid of Giza representing Egypt and the Riyadh TV Tower representing modern Saudi progress — uniting past and present. The upper right corner bears the Saudi national emblem of crossed swords and a palm tree. This stamp celebrates cultural exchange and the modernization of the Kingdom through international cooperation.
