Traditional Mexican handcrafted toys are those made by artisans rather than manufactured in factories. The history of Mexican toys extends as far back as the Mesoamerican era, but many of the toys date to the colonial period. Many of these were introduced as teaching tools by evangelists, and were associated with certain festivals and holidays. These toys vary widely, including cup and ball, lotería, dolls, miniature people, animals and objects, tops and more—made of many materials, including wood, metal, cloth, corn husks, ceramic, and glass. These toys remained popular throughout Mexico until the mid-20th century, when commercially made, mostly plastic toys became widely available. Because of the advertising commercial toys receive and because they are cheaper, most traditional toys that are sold as handcrafts, principally to tourists and collectors.
