Gotlib's first series were made in a very humoristic tone. Each story consisted of two to four strips drawn in white and black. "Rubrique-à-Brac" and "Les Dingodossiers" consisted of didactic dossiers of short unrelated strips, drawn in black and white. They revisited an extremely wide range of subjects and dealt with stereotypes and clichés in a caricatural way. Gotlib used caricature and parodies to depict the everyday life, and greets it with extreme derision. In "Cinemastok" and "Gai-Luron", the same technique was used, although these series were presented in a different manner.
