Cartonería or papier-mâché sculptures are a traditional handcraft in Mexico. The papier-mâché works are also called "carton piedra" (rock cardboard) for the rigidness of the final product. These sculptures today are generally made for certain yearly celebrations, especially for the Burning of Judas during Holy Week and various decorative items for Day of the Dead. However, they also include piñatas, mojigangas, masks, dolls and more made for various other occasions. (Wikipedia)
