You can not write about Posada without thinking of Manuel Manilla, his artistic mentor. Both are extremely important for the development of Modern Art in Mexico. He has been a great influence to Diego Rivera. I am still searching for the reason why van Gennep published 2 very important monographic titles on Manilla and Posada. Is it interest or because of the worldwide reach of these publications that he thought these were interesting?….i really do not know.
Academics have estimated that during his long career, Posada produced 20,000 plus images for broadsheets, pamphlets and chapbooks. Posada was studied by key figures of Mexican muralism. Mural artists inspired by Posada, such as Diego Rivera and José Clemente Orozco catered to a Mexican elite that rejected foreign styles as part of their new-found bourgeois taste.
Posada is now a part of the Mexican art legacy and just a quick look into the book that is now for sale at http://www.ftn-books.com shows immediately why his art is timeless and a part of the Mexican folklore.
