National Day 1991 - The Year of Industry - 400 baisa
Issued in 1991, this stamp commemorates Oman's 21st National Day, celebrated on 18 November 1991, which was officially designated as "The Year of Industry." The design features the national emblem of the Sultanate of Oman at the center of a cogwheel motif, surrounded by symbols of major industrial sectors, including oil refining and petrochemicals, manufacturing facilities, maritime industry, and industrial development projects. The cogwheels and industrial imagery reflect Oman's commitment to expanding its industrial base and diversifying its economy beyond traditional sectors.
During the late twentieth century, Oman pursued an ambitious program of industrialization aimed at strengthening manufacturing, energy production, infrastructure, and economic self-sufficiency. The designation of 1991 as the Year of Industry highlighted the government's emphasis on industrial growth as a key component of national development and long-term economic planning.
By issuing this commemorative stamp, the Sultanate of Oman celebrated the achievements of its industrial sector and underscored the importance of economic diversification, technological progress, and industrial investment. The issue recognized the contribution of industry to employment, modernization, and national prosperity, while reflecting Oman's vision for sustainable economic development and continued growth into the future.
