Issued in 1952 for Día del Sello Colonial (Colonial Stamp Day), this Spanish Sahara stamp features a striking close-up of an ostrich’s head, beautifully engraved in a deep carmine tone. The 10+5 céntimos denomination reflects both postal value and a charitable surcharge supporting colonial postal development. Printed by the Fábrica Nacional de Moneda y Timbre (F.N.M.T.), this issue highlights the rich fauna of the Sahara and symbolizes Spain’s philatelic outreach in its overseas territories during the mid-20th century.
