Two Catrina figurines, approximately 38 cm (15 in) tall in the City Museum of León, Guanajuato, Mexico. Popularized by José Guadalupe Posada, the Catrina is the skeleton of an upper class woman and one of the most popular figures of the Day of the Dead celebrations, which occur across two days, on November 1–2, corresponding with the Catholic holy days of All Saints' Day and All Souls' Day. It has its origins in an Aztec festival dedicated to the goddess Mictecacihuatl, which is represented by the Catrina.Photo credit: Tomas Castelazo
