L'homme aux Phylactères, 1980.

Serge Gennaux is a Belgian comic artist, who is best-known for his humorous comics for Spirou magazine. He began his career working in the realistic genre, however, with the hard-boiled illustrated serial 'Du Grisbi en Vrac' for Héroic Albums, before becoming the apprentice of Maurice Tillieux in 1957. Two years later, he joined the art studios of the publishing house Dupuis, where he was initially assigned to do the lettering for Robbedoes, the Dutch equivalent of Spirou magazine. Text (c) Lambiek
