One of the characters mentions reading 'Buck John'. These are a series of western adventures published in France, with the full title 'Buck John le bayard de Far West'. The English versions were published under the title 'Buck Jones' by Cowboy Comics (a Fleetway publication). They are based on the silent movie star, Buck Jones. Prior to his death, he had given permission for his name to be used in a comic book series. The series ran until around 1953 (USA) and was a important source of income for his widow Odille.
