Far from the idea of decorating the city, Escif sees his murals as pretexts for exchange. The context is for him one of the essential ingredients, the imagery that emerges above all at the service of the dialogue that he wishes to engage with the passers-by. During a workshop with the students of the Pasteur High School, Escif wondered if new walls should be built to protect the Unesco listed walls. He then reproduces this listed railing seen on the balcony of the house.
