Issued in 1957 by Spanish Sahara, this commemorative stamp celebrates Día del Sello (Day of the Stamp). It features a finely engraved image of the striped hyena (Hyaena striata), a species native to North Africa and the Sahara region. The brown monochrome design shows the animal in motion, highlighting its distinctive striped coat. With a face value of 15 céntimos + 5 céntimos surcharge, the additional charge supported postal initiatives. Printed by the F.N.M.T. (Fábrica Nacional de Moneda y Timbre), this stamp is a valued piece for collectors of colonial issues, wildlife themes, and Spanish territories.
