Inauguration 1st Petrol Pipeline - 50 millieme

Issued in 1961, this stamp commemorates the inauguration of Libya's first petroleum pipeline, opened on 25 October 1961, linking the Zelten oil field (now Zella/Intisar field area) to the export terminal at Marsa el Brega. The completion of the pipeline marked a major milestone in the development of Libya's oil industry, enabling the efficient transportation of crude oil from inland production areas to the Mediterranean coast for export to international markets.

By issuing this commemorative stamp, the United Kingdom of Libya celebrated a turning point in the country's economic history. The issue highlighted the growing importance of the petroleum sector in national development and recognized the role of modern energy infrastructure in supporting economic growth, industrial progress, and Libya's emergence as a significant oil-producing nation during the early 1960s.
