Maurin received the support of Vollard and was a friend of Toulouse-Lautrecwho had his first individual exhibition with him in 1893and also of many other artists, including François-Rupert Carabin and the entertainer Aristide Bruant. A notable symbolist work of his is "Maternity", a study of motherhood. Inspired by Japanese artists, he revolutionized the technique of etching, but without forgetting the woodcuts. In 1891 he patented a method of color printing. In 1892, he exhibited at the Salon de la Rose + Croix. He contributed to "La Revue Blanche", directed by Félix Fénéon, and "Les Temps nouveaux", published by Jean Grave.
