Guillermina Aguilar is a well documented Master of Mexican Popular Art. Guillermina is the eldest of the Aguilar sisters of Ocotlan, Oaxaca. Guillermina's sisters are Josefina, Concepcion and Irene Aguilar. From an early age, the famed Aguilar sisters learned to make clay figures from their mother. Their work today is world famous and highly sought after by Folk Art Collectors.

Guillermina, Josefina and Irene and Concepcion have transformed traditional clay making into new and magical forms. Their clay figures are exhibited widely in galleries and museums both in Mexico and abroad.

Guillermina's work is illustrated in two important books on Mexican Folk Art:"Oaxacan Ceramics:Traditional Folk Art by Oaxacan Women" and in the exemplary Banamex book:"Great Masters of Mexican Popular Art" (Banamex Collection Fomento Cultural). The art that comprises the extraordinary Banamex book is being exhibited throughout the world and was shown in New York City at the Smithsonian National Museum of the American Indian (NMAI), March 2003.
