This 40-cent South African postage stamp, issued in 1993, features the Riverine Rabbit (Bunolagus monticularis), one of the world’s rarest and most endangered mammals. Illustrated by Denis Murphy, the design portrays the rabbit resting in its semi-arid habitat along the Karoo riverbanks, surrounded by native vegetation. The bilingual inscription “South Africa / Suid-Afrika” reflects the country’s linguistic duality during the early post-apartheid era.

For collectors, this issue is part of a notable wildlife conservation series that highlights South Africa’s unique fauna. The Riverine Rabbit, endemic to the Karoo region, symbolizes the importance of ecological preservation and is a highly sought-after subject among thematic collectors focused on endangered species.
