Issued in 1956 for Día del Sello (Stamp Day), this 70 céntimos commemorative from Guinea Española features the colonial coat of arms, finely engraved by the Spanish F.N.M.T. The central vignette displays Pico Basilé, the dominant volcanic peak of Bioko Island, surrounded by heraldic lions and castles representing Spain. Lances, fasces, and decorative scrolls frame the design, adding strong colonial iconography. Printed in rich olive-green intaglio, it is a notable mid-century issue from Spain’s African territories and sought after for its sharp engraving and historical context.
