This attractive 1952 commemorative pair from Ifni was issued for the Día del Sello Colonial (Colonial Stamp Day) and features an elegant seabird perched on a rock, rendered in a finely engraved classical style. The stamps include surtax values (+5 and +15 céntimos) intended for charitable or promotional philatelic purposes, a common practice in mid-20th-century Spanish colonial issues. Printed by the Spanish National Mint (F.N.M.T.), the contrasting green and carmine colorings create a visually balanced set that is popular among collectors of colonial, wildlife, and Spanish-area philately. Well-centered mint examples such as these are appreciated for their clean perforations and detailed engraving.
