Les diamants de l'archiduc

In 2007, French publisher Ouest-France launched Les diamants de l'archiduc, a single-issue historical comic that spins a jewel-heist tale around the Archduke's diamonds. This standalone volume offers a self-contained, richly illustrated narrative typical of the publisher's line of accessible, fact-inspired bandes dessinées. Though a brief entry, it showcases Ouest-France's commitment to blending adventure with European history in a compact, visually engaging format.
