National Day - Sultan and his Crest
Issued in November 1981 alongside the Al-Razha issue to celebrate the 11th National Day of the Sultanate of Oman, this highest-value 300 Baisa commemorative stamp honors the country's sovereign leadership and territorial integrity. Flawlessly produced by the Swiss security printer Courvoisier, the stamp's upper corners display the denomination symmetrically, with "300 BAISA" on the left and the Eastern Arabic numeral equivalent (٣٠٠ بيسة) on the right. The lower margin cleanly integrates the celebratory milestone in both languages, inscribed as "NATIONAL DAY 1981 / العيد الوطني ١٩٨١ م".
The central design features a stately portrait of Sultan Qaboos bin Said wearing traditional Omani dress and a colorful turban (massah), superimposed directly over a green geographical map of the Sultanate. The portrait is flanked by two burning ceremonial candles wrapped in the colors of the Omani flag, all beautifully framed within a golden laurel wreath of peace and victory. Crowned at the top center by the national emblem the crossed swords and ceremonial khanjar this key philatelic issue was leveraged by administrative authorities to visually anchor the Sultan's leadership as the central catalyst for unity, sovereignty, and rapid infrastructural development across all provinces of modern Oman.
