This striking commemorative issue from Spain was released to promote the Barcelona International Fair (CIF 60) and features the iconic Basílica de la Sagrada Familia, Antoni Gaudí’s world-famous architectural masterpiece. The set highlights the soaring towers and sculptural façade of the basilica, rendered in elegant monochrome engraving against different colored backgrounds for each denomination (80 cts, 10 ptas, and 250 ptas). Produced by the Spanish National Mint (F.N.M.T.), these stamps combine architectural significance with mid-20th-century Spanish commemorative design, making the complete set highly desirable for collectors of architecture, Spain, and thematic city landmarks.
