Gabi Grün - Das Horn der Rhinos

In 1995, the WWF (World Wide Fund for Nature) launched Gabi Grün – Das Horn der Rhinos, a single-issue German-language comic that uses its story to spotlight rhinoceros conservation. Illustrated by René Lehner, the comic follows the young environmentalist Gabi Grün as she tackles the threat of poaching. Though brief, this issue stands as an early example of using the comic medium for direct wildlife advocacy, blending adventure with an urgent ecological message.
