Catrinas are made all over Mexico and were originally inspired by the famous "La Catrina" of Jose Guadalupe Posada, who depicted a very well dressed woman at the turn of the century as a skeleton. Since then, she is seen all over the country as almost the national symbol of Dia de Los Muertos. You can even find her in Diego Rivera's mural, "Sunday Afternoon in Alameda Park." There is a village in the state of Michoacan which specializes in clay catrinas, such as the one on the left, and the term generally now includes any well dressed skeleton. We usually have catrinas in clay, paper mache, wire, and wood. They are among the most loved pieces in Mexican folk art.
Catrina on the left is by Domingo Neri.
