One of the first people to publish a reference about Jose Guadalupe Posada and Antonio Vanegas Arroyo was Mexican painter, printmaker, writer and some say also a volcanologist, Gerardo Murillo (Jalisco, Guadalajara, b. 1875 - d. 1964). He signed his works as "Dr. Atl" (atl = the Nahuatl word for water). Pictured here is the front cover to the two volume set of Los Artes Populares de Mexico published in 1922; five years after the death of Antonio Vanegas Arroyo and nine years after the death of Posada. In the second volume Dr. Atl briefly reviews printmaking and aspects of literature such as songs, religious works and what might be called "tabloid-like" publications of Mexico. The publishing house of Vanegas Arroyo is discussed and
grabador "Guadalupe Posadas" is very briefly mentioned; significantly, the printing house is described as one of the leading printing establishments of it kind and for the time. A variety of Posada's images are pictured in the volume, some of the engravings/etchings are signed by Posada and some unassigned images are also reproduced.
