This French commemorative stamp was issued in 1974 to mark the 100th anniversary of the Club Alpin Français (French Alpine Club), founded in 1874. The design features a rugged mountain peak, symbolizing the Alpine environment, and a blue alpine flower, likely a gentian, associated with high-altitude flora. The stamp, denominated at 0.65 francs, highlights France’s mountaineering heritage and the club’s role in promoting mountain exploration and preservation. Designed by M. Monvoisin, it combines natural beauty with alpine tradition.
