Calaveras, or skulls, are often associated with the celebration of Día de los Muertos, a Mexican holiday honoring deceased loved ones. They are typically made from sugar, clay, or other materials and are decorated with vibrant colors and intricate designs. These decorative skulls symbolize the cycle of life and death, reminding people to celebrate rather than mourn those who have passed. In art and culture, calaveras are prominent in Mexican folk art and literature, often depicted in various forms, including paintings and sculptures. They serve as a reminder of mortality and the importance of remembering and honoring the dead in a joyful manner.
