 From that point, Van Melkebeke worked under the pseudonym George Jacquet or as a ghostwriter, on such projects as "Tintin", Laudy's strip "Hassan et Kaddour", and Paul Cuvelier's "Corentin".In the mid-1950s Van Melkebeke worked on a new children's comic strip called "Les Farces de l'Empereur" for "Ons Volkske"/"Chez Nous".In 1954, Van Melkebeke suggested to Hergé the idea of setting "Tintin in Tibet" (1958–1960) in that country, possibly being influenced by the fact that he had set the play "Mr. Boullock's Disappearance" there.
