Issued in 1937 by French Equatorial Africa, this striking 30 centimes stamp features a detailed engraving of the black rhinoceros (Diceros bicornis) in its natural habitat, accompanied by lush vegetation and a snake entwined among the plants. Designed and engraved by master artists, the monochrome design highlights both the power of the rhinoceros and the dangers of the wild African environment. As part of the colonial wildlife definitive series, it reflects the French colonial fascination with Africa’s exotic fauna. This issue is especially valued for its artistic engraving and classic colonial-era aesthetics, making it a desirable addition for collectors of African wildlife and French colonial philately.
