This 15 céntimos black stamp was issued by Spain in 1930 to commemorate the Ibero-American Exposition of Seville, held to promote cultural and economic ties between Spain and Latin America. The design features the Dominican Republic pavilion, highlighting the participation of Latin American nations in the fair. The stamp bears the inscription “Pro Unión Iberoamericana” (For Ibero-American Union), symbolizing solidarity among Spanish-speaking countries. Issued as part of a larger commemorative series, these stamps are prized by collectors for their historical value and architectural depictions. Well-centered examples with clean perforations are especially desirable.
