Folk art
The centennial of the end of the Mexican War of Independence in 1821 prompted two major exhibitions of Mexican folk art, one in Mexico City and the other in Los Angeles. These were conceived of by Roberto Montenegro and Jorge Enciso, with help from Xavier Guerrero, Adolfo Best Maugard and Gerardo Murillo or Dr Atl. At this time period, Dr Atl published a two-volume work called "Las artes populares de México" (Folk arts of Mexico) which became an authority on the subject. This survey included discussions on pottery, fired-clay earthenware, toys, silverwork, goldwork, feather mosaics, basketry, textiles, wood objects, folk religious paintings called ex-votos or retablos as well as other folk art expression such as theater, poetry and printmaking.
