The LE MATIN / LE FILS DE PARDAILLAN poster is a poster for a popular historical novel by Michel Zevaco (1860 – 1918) which was serialized by Le Matin around 1906.
The book was one of a series of novels by this popular journalist, novelist, publisher, film director, anti-clerical anarchist. He was, as one might surmise, a controversial character.
In this scene from the novel Jehan-le-Brave (Le Fils of the title) has come to the rescue of Bertille of Saugis, the natural daughter of Henry IV. The criminal, Ravaillac, hired by the Jesuit superior to kidnap her, lies defeated and securely bound in the background. This is high drama poster art.
