Guillermina Aguilar Alcántara is the first-born daughter of Isaura Alcántara Díaz, the woman who started the Aguilar family's clay tradition. She grew up helping her mother with the household and never had a formal education, learning the craft instead by working alongside her. What she considers her own special contribution is the faces: strikingly expressive, often the first thing you notice on one of her pieces. Frida Kahlo is a recurring subject for her, along with whimsical water jugs shaped from clay. Her work has earned her a place in books like "Grandes Maestros del Arte Popular Mexicano," and in a career now spanning more than five decades, her pieces have found homes in collections across Mexico, the U.S. and Europe.
