This 15 céntimos black stamp was issued by Spain in 1930 to commemorate the Ibero-American Exposition of Seville. The design features the Dominican Republic pavilion, symbolizing the shared cultural and historical ties between Spain and Latin America. The inscription “Pro Unión Iberoamericana” highlights the spirit of unity among Ibero-American nations, while the event name “Sevilla 1930” marks its origin. Ornamental coats of arms frame the vignette, adding to its official commemorative tone. Highly sought after by exhibition-themed and Spain–Latin America collectors, this issue reflects Spain’s effort to strengthen ties with its former colonies.
