Issued by Equatorial Guinea, this 0.15 Ekuele stamp commemorates the Año Santo (Holy Year) 1975, featuring an architectural view of El Duomo of Udine, Italy. The bold magenta and sepia engraving highlights the cathedral’s Romanesque-Gothic façade with rose windows and arched portals. Designed with strong linework and dramatic perspective, it captures both religious heritage and European sacred architecture. Part of a thematic Holy Year series popular with church and Vatican topical collectors. A distinctive piece for faith, architecture, and international commemorative collections.
