On the occasion of the one hundredth anniversary of the death of José Guadalupe Posada (18521913), a group of historians and writers reflect on various aspects of his life and work. This volume contains essays by Juan Villoro, Helia Bonilla, Monserrat Galí, and Rafael Barajas, as well as a study by Mercurio López Casillasthat organizes a significant part of Posadas work chronologically and in terms of the printmaking techniques employed. It also includes two complementary sections: one that examines the technical transition from lead to zinc in engraving and a second that gives examples of the iconographical sources drawn on by Posada. The book contains almost one thousand reproductions of original prints of the period, including dozens of engravings never before published in book form. Owing to the quality of the texts, the book design, the selection of works, and its meticulous production values, Posada. A Century of Skeletons promises to be an indispensable contribution to the centennial celebration.
