WallDecaux: Mercedes Key To Viano Campaign

Mercedes-Benz Vans with the slogan "Key to Viano"offer the unprecedented opportunity to control digital advertising displays using their own remote car keys. Every time a remote car key -- no matter for which brand of car -- was operated, the side door of a digital Viano opened, and different kinds of passengers descended the vehicle: sometimes weird, sometimes colourful, sometimes from another world.
