The 75 members of the Comité Colbert, which groups French luxury brands such as Louis Vuitton, Hermès and Chanel, have launched a wide-ranging campaign to fight counterfeiting throughout Europe, where the black market has thrived thanks to the internet. With the help of customs agents at 18 airports throughout France, the committee will use posters and brochures to publicize the fact that if someone buys a counterfeit product, he or she can be held liable. The seven different posters take a humorous tone, with one depicting a fake Chanel cell phone and reading, “With this phone, you can call your lawyer.” The committee has the support of officials in Italy, the Czech Republic, Hungary, Slovakia, Romania and Croatia, and has adapted posters for each country. France is the only country where owning counterfeit products is considered an offense. Counterfeiting costs the country more than 30,000 jobs and €6 billion per year, according to the committee. Louis Vuitton is the most popular target of counterfeiters.
