Jean-François de Marchin began his career in the Carte Blanche section of magazine Spirou in 1974. In the early 1990s, he was present in Hello Bédé with the series 'Harold et Pétula'. In 1992, he cooperated with François Walthéry and Stibane Serd on an album of 'Petit Bout d'Chique'. De Marchin and Walthéry have also illustrated some books in the collection 'Contes et Légendes de Chez Nous' together.
In 1990 De Marchin paid graphic tribute to François Walthéry in the collective homage book 'Natacha. Special 20 Ans' (Marsu Productions, 1990), which celebrated the 20th anniversary of Walthéry's series 'Natacha'.
