Julio Ruelas (June 21, 1870 – September 16, 1907) was a Mexican graphic artist, painter, draughtsman and printmaker. Ruelas was the principal illustrator of the magazine and is most associated with Mexican symbolism. A number of his works are on display at the Museum of the City of Mexico and in the Zacatecas museum. Artistically, he was noted for creating etched images depicting his own face, incorporating black, twisted lines to give an impression of being tormented.
