Lupita dolls, also known as cartonería dolls, are toys made from a very hard kind of papier-mâché which has its origins about 200 years ago in central Mexico. They were originally created as a substitute for the far more expensive porcelain dolls and maintained popularity until the second half of the 20th century, with its availability of plastic dolls. Today they are made only by certain artisans’ workshops in the city of Celaya, as collectors’ items. Since the 1990s, there have been efforts to revitalize the crafts by artists such as María Eugenia Chellet and Carolina Esparragoza sponsored by the government to maintain traditional techniques but update the designs and shapes.
