This striking purple postage due stamp from the République du Niger features the Croix d’Agadez (Cross of Agadez) — a traditional Tuareg symbol of cultural identity and craftsmanship from northern Niger. Issued as part of a timbre-taxe series, it was used to indicate unpaid postage on mail. Designed by G. Aufschneider and engraved by Delrieu, the issue highlights Niger’s heritage through intricate local artistry. Its geometric design and rich violet tones make it one of the most distinctive African fiscal issues of its period.
