After the liberation of Belgium in September 1944, there was a boom of new magazines for the youth, both in French and Dutch. Many of those tried to mix American comics with local artists. Vandersteen worked in these early years for countless publications. He continued publishing in "Bravo", with the medieval gags of "Lancelot". Having moved to the suburbs of Brussels to avoid the bombardments of Antwerp, he came into contact with some French language editors. French language magazines he contributed to included "Franc Jeu", "Perce-Neige", and "Le Petit Monde". Two of the comics he created for "Franc Jeu" were also published in albums. By 1947, all these magazines had disappeared.
