In 1948, Belgian creators, and three of the famed gang of four and creators of the Marcinelle school of comic book art, Morris, Jijé and Franquin, traveled to the USA, to see the country, and what was left of the Wild West. This would inspire Morris' creation Lucky Luke.
Over sixty years later, it would also inspire another comic book, Gringos Locos, about their adventures in America. It was a hotly anticipated graphic album and had been partially serialised in Le Soir.
Which is how the heirs of Morris, Jijé and Franquin heard about it.
Le Vif is reporting that, as a result of legal action brought by the heirs of the featured creators, publisher Dupuis has put the sale of the book on hold before it reached the bookshops, and may be forced to pulp 35,000 of the hardcover volumes.
Which also means that the copies released to the press will be worth a small fortune. Here's a preview of the comic, and a motion comic trailer of Gringos Locos.
