This 30 pesetas commemorative stamp, issued by Correos España in 1996, is part of the Minerales de España (Minerals of Spain) series. It depicts a miners’ safety lamp from the Museo de la Minería y de la Industria de Asturias (MUMI) — a tribute to Spain’s deep mining heritage. Behind the lamp, a detailed engraving of a mine tunnel evokes the industrial landscapes of Asturias, one of the country’s most important coal-mining regions.

Designed and printed by F.N.M.T. (Fábrica Nacional de Moneda y Timbre), this issue highlights Spain’s technological contributions to mine safety and honors the workers who toiled underground to fuel the nation’s growth.
