This 40-centime stamp from the République Rwandaise was issued in 1970, depicting the majestic Mountain Gorilla (Gorilla beringei beringei) — one of Africa’s most iconic and endangered species. The design, illustrated by J. Van Noten, features a striking black-and-pink composition, with the gorilla rendered in detailed engraving against an expressive brush-styled jungle backdrop.

Issued at a time when Rwanda was emphasizing its rich natural heritage, this stamp belongs to a broader wildlife-themed series celebrating the fauna of Central Africa. Its elegant minimalist layout, bold typography, and scientific inscription “Gorille de montagne” reflect Rwanda’s early philatelic style that merged art with conservation awareness.
