National Day 1975 (Mina Raysut) - 30 baisa

This stamp celebrates Oman's 5th National Day in 1975 by highlighting a major infrastructural milestone in the southern Dhofar region: the development of Mina Raysut (later expanded as the Port of Salalah). The detailed illustration showcases the newly constructed concrete breakwater, mechanized harbor cranes, and a fleet of traditional dhows paired alongside modern commercial vessels. An official portrait of Sultan Qaboos bin Said in a military peaked cap is positioned in the upper right corner, framing this southern industrial project as a triumph of national unity, territorial security, and regional economic integration following the stabilization of Dhofar. The issue projects an image of robust economic self-determination, positioning Raysut as a strategic gateway for regional trade and resource management.
