Bertrand Dupont drew the 'Modeste et Pompon' series in Tintin from 1976 to the early 1980s. The series was created by André Franquin in the 1950s, and has been drawn by artists like Attanasio, Mittéď and Griffo since. Several gags were written by Bob de Groot. He was succeeded by Walli, with whom he also cooperated on the series 'Touky le Toucan'.
