Adrien Barrère (1877-1931), was a French poster artist and painter, active in Paris during the Belle Époque. After studying the law and medicine, Barrère turned to illustrating and particularly to the art of caricature, also designing a large number of posters for Parisian cinemas and Grand Guignol. Barrère chronicled and caricatured performers of the Paris stage, adopting a kindlier approach than that of Toulouse-Lautrec.
