Udolfo - La Montre aux 7 rubis

Editions Jonas launched the Franco-Belgian mystery series Udolfo - La Montre aux 7 rubis in 1980, a single-issue comic that blends adventure with a jewel-toned puzzle. Centered on a watch adorned with seven rubies, the story unfolds as a self-contained enigma, showcasing the publisher’s penchant for atmospheric, illustrated storytelling. Though brief, this standalone entry remains a curious artifact of early-80s European comics.
