For the new edition of the European Researchers' Night, La Rotonde (centre of mediation and scientific culture - École Nationale Supérieure des Mines de Saint-Étienne) renewed its confidence in us and entrusted us with the creation of the flyer (relaying the communication announcing the evening) and a booklet distributed on the spot in order to accompany the spectators during the event. It listed all the activities organised and could be used by the spectator as a souvenir booklet thanks to the slots for the stickers distributed by the researchers met.
