This classic French Guiana colonial stamp features the iconic Giant Anteater design, originally part of the definitive fauna series symbolizing the region’s natural wildlife. During World War I, it was overprinted with a Red Cross emblem and “5” surcharge, indicating an additional charitable fee collected to support Red Cross wartime relief efforts. Such surcharged issues reflect the humanitarian postal history of French colonies during global conflict. The bold red typographic design combined with the emergency overprint makes it highly desirable among collectors of colonial, Red Cross, and WWI postal issues. Genuine examples are appreciated for clear surcharge impressions and intact perforations.
