National Day 1975 (Watayah Stadium) - 50 baisa

This stamp celebrates Oman's 5th National Day in 1975 by highlighting civic sports infrastructure, modern entertainment, and national unity. The central illustration features the newly built open-air stadium at Al-Watayah, superimposed over an golden map of the Sultanate that shows a broadcasting tower transmitting signal waves. In the lower-right corner, traditional Omani folk musicians are shown singing and playing a rabuba drum, carrying a powerful message of harmony between ancestral folklore and modern national life. With the official military portrait of Sultan Qaboos bin Said anchoring the top-right corner, the composition frames the construction of modern public gathering spaces as a core achievement of the early Omani Renaissance (Al-Nahda), uniting the territory's diverse regions through shared cultural and athletic pride.
