The event, organized by the bookstore La Case à Bulle in partnership with the media library, attracted over 150 fans. The program included a signing session followed by a conference on the creation of this new comic, which continues Franquin's legacy. Gaston Lagaffe himself was present for the enjoyment of children and adults, participating in photo opportunities.
Fun activities were offered for younger attendees, giving them a chance to win discount vouchers. These included a quiz, a game to guess the number of paperclips in a jar, and a contest for the most useless invention drawing.
