What is "l'ymagier"

L'Ymagier, subtitled "A Magazine of Engravings", was a French symbolist art magazine edited by Alfred Jarry and Remy de Gourmont between 1894 and 1895. It ran for five issues and disbanded one year after its first printing, but in that time it published many prints and engravings by influential artists of the time, including Henri Rousseau.
