Luc Lafnet was a Belgian painter and illustrator, and the regular assistant of his close friend Blanche Dumoulin and her husband Robert Velter on their comic strips. He studied at the Academy of Fine Arts in his birth city Liège and was active as an etcher and painter of mainly religious scenes in the Montmartre area of Paris since 1923. He also made illustrations for books (by Georges Simenon, among other writers) and children's magazines, for which he used a variety of pseudonyms, such as Lucan and Lafcat for his advertising work, Grim, Jim Black, Lucas O, Rich, Pol or Viset for his erotic work and Davine for his comics.
