25th Anniversary of the Arab Postal Union - 75 baisa

This stamp commemorates a major landmark in pan-Arab diplomacy and administrative collaboration: the silver jubilee (1952–1977) of the Arab Postal Union (APU). The central design features a prominent, circular wreath composed of the interwoven flags of the member states, enclosing a central medallion that illustrates a carrier pigeon bearing a letter above a traditional postal horn. The composition carries a powerful message of regional integration, shared communication networks, and institutional unity across the Arab world. Symmetrically framed by delicate Islamic arabesque scrollwork patterns in a vibrant green border, the design proudly anchors Oman's post-1970 postal services and bureaucratic infrastructure within a broader framework of regional solidarity and logistics management.
