An angel, a sumo wrestler, a sculptor, a bird, a guitarist... you visualize these characters on geometrical shapes and you know that this is the work of Clet Abraham. This artist has fun hijacking traffic signs with a touch of humor. Yet there is a real message: the artist seeks to criticize the signs because from his point of view, they are the first signs of rules and order. In Mulhouse, there are more than 200 of them! So raise your head to find them, but watch out for the road!
