("Need an expert on the products of the stock exchange? Meet our teams and make the difference witht the number one")
I first saw such type of communication support at the Charles de Gaulle airport for the rugby world cup. This time was the Palais des Congrès where I went to visit an exposition on investment (the ad is about a French bank).
What was interesting, was that once inside you could still see the ads because the doors were transparent and the ads were in plastic.
An interesting and new support to consider.
