In 1965 Gotlib submitted strips to "Pilote" magazine and was greeted with open arms by its influential co-founder and editor, René Goscinny of "Astérix" fame. Together they created "Les Dingodossiers", a series of mock lectures on random subjects which Goscinny wrote and Gotlib drew. In 1967, Goscinny, who worked on many strips simultaneously while editing the magazine, asked Gotlib to continue the series alone. Gotlib instead launched a new one, "Rubrique-à-Brac", which was similar to the Dingodossiers in format but progressively acquired a more adult and less formal tone. Leftover pages from both series were later published in album form as "Trucs-en-vrac".
