French bloggers have been put off by a McDonald's ad featuring Gallic independence symbol Asterix and his merry band of warriors feasting inside one of the US fast food giant's restaurants.
One Internet commentator said the poster, which has sprung up on French streets this week, was "an electric shock" and asked how the authors of the phenomenally successful comic series could have allowed such use of Asterix.
"I don't know what to say except express my deep disgust," wrote Georges Abitbol on the veilleurs.info website. "If this doesn't cause traffic accidents..."
"Well done Albert Uderzo for sacrificing such a comic book monument to the Roman hordes," wrote Abitbol, referring to the illustrator who created the indomitable characters along with late writer Rene Goscinny over 50 years ago.
Since then, the comic book adventures of the first century BC warrior have sold 325 million copies -- 200 million of them abroad -- and been translated into 107 languages and dialects.
The 20-year-old Asterix theme park outside Paris rivals the French capital's Disneyland as a tourist draw and a series of hit movies, including both live action and animated capers, have been worldwide hits.
The contentious ad shows the village partying, as is traditional at the end of one of Asterix's and his sidekick Obelix's adventures, inside the restaurant, with the bard Cacophonix tied up at the foot of a tree, also a tradition.
