This commemorative stamp from Spain was issued in 1988 to mark the centenary celebration of the historic royal title Prince of Asturias, traditionally granted to the heir to the Spanish throne. The design features a medieval-style illustration of Enrique III of Castile, recognized as the first Prince of Asturias, seated beneath an ornate canopy. The stamp also displays the symbolic Cross of Asturias and Gothic lettering, emphasizing Spain’s royal heritage. Printed by the Fábrica Nacional de Moneda y Timbre (F.N.M.T.), it carries a denomination of 20 correos. A historically themed issue, this stamp is a notable addition for collectors interested in Spanish monarchy and royal commemoratives.
