Arab Palm Tree Day - 100 baisa
Issued on September 19, 1982, the Arab Palm Tree Day commemorative stamp set from the Sultanate of Oman celebrates the profound cultural, agricultural, and economic significance of the date palm (Phoenix dactylifera) across the Arab world. Released in alignment with regional initiatives to promote sustainable oasis agriculture and safeguard indigenous plant genetics, this two-stamp series highlights the tree as a historical symbol of endurance and life in the hyper-arid landscapes of the Arabian Peninsula. Expertly produced by the Swiss security printing firm Courvoisier, the issue features highly detailed illustrations celebrating the cultivation and harvest of this vital natural resource. Symmetrically framed in the classic format of Oman's early-1980s commemorative releases, the design elegantly integrates the country title in both English and Arabic script, the national emblem of crossed swords and a khanjar, and a portrait medallion of Sultan Qaboos bin Said. By dedicating a high-profile philatelic issue to Arab Palm Tree Day, the Omani administrative framework underscored its commitment to traditional agrarian heritage, environmental stewardship, and regional food security milestones during a decade of sweeping national transformation.
