We set up warning signs throughout the city at highly frequented locations. But their meaning was not clearly understandable just by the icons. Therefore the knowledge of a foreign language was necessary.People, who didn’t know the language in question but wanted to know the meaning of the signs, had the possibility to follow our request, make a photo of the sign with their mobile phone and send it to Berlitz.

Never before were danger signs noticed and photographed with such attention. Traffic on the Berlitz homepage increased by 3% during the period of the campaign; even the booking of language courses increased by 8 %. The budget for 60 signs amounted to only 9,000 Euros.
