Tiercy leaves the Carillon in 1895 and is replaced by Bertrand Millanvoye, dramatic author and journalist. Millanvoye hires the young and ambitious Henri Dreyfus, who had just made his first appearance under the stage name of Fursy. Things move very rapidly during these years of nightlife madness, In the summer Fursy creates the Carillon Court in the adjoining garden. This travesty of a court met with enormous popularity and gave Courteline, a regular patron, the idea for one of his best successes: “Un client sérieux”. In this poster Grün adopts the black background that will become his hallmark and adds the color red, admittedly natural for the magistrates, but which he will favor from now on.
