This striking 10 + 5 céntimos stamp was issued in 1957 by Spanish Sahara to mark Día del Sello (Stamp Day). It features a detailed portrait of the Striped Hyena (Hyaena striata), an animal native to parts of North Africa. The bold magenta tone enhances the dramatic look of the hyena’s head, with its sharp teeth and watchful gaze. The surcharge (+5 cts) went towards supporting postal services, a common practice of the period. A beautiful piece from the colonial issues of Spain’s overseas territories, it is prized by collectors of African fauna and Spanish Sahara philately.
