[1] In that time, he created many comics heroes and published some animal stories at Fleurus editions.

In 1964, he created with Henriette Robitaillie the series Bec-en Fer published in Le Pelerin.

This series, in which he denounced comically violence, malice, stupidity and fanaticism, was dedicated to older persons.
