The Bétonpapier is a mediation medium in the form of a risograph-printed poster. Dedicated to 6-11 year-olds, it accompanies young and old alike in their discovery of the current exhibition. As they unfold the poster, young visitors are invited to wander around the exhibition, focusing on one detail or another, expressing themselves through drawing, writing or play. The visit is punctuated by games and riddles, with plenty of room for autonomy and wandering around the exhibition space.
