In 1957, Henry Blanc became one of the main providers of daily comic strips for newspaper France-Soir. His daily feature 'Le Jeu des 7 Erreurs' started in 1959 and ran for more than 30 years. Between 1957 and 1960, he produced a comic strip adaptation of 'Signé Furax' with writer Robert Mallat. Furax was a famous French radioplay by Pierre Dac and Francis Blanche at the time. Blanc drew 1174 strips of the comic. Later on, he also made comic adaptations of 'Le Jugement Dernier', 'Les Mystères de Paris 1962' and 'Les Enquêtes du Commissaire San-Antonio' for the paper.
