Question: who made up the day of the dead

title: Calavera
text: Other calaveras are produced to be edible . Most are cast as one piece from cane sugar ( which can either be left unflavored or flavored with vanilla ) . Other calaveras may be made from chocolate . The calaveras are typically colored with vegetable dyes . Like the more decorative calaveras , these will sometimes have names written on the foreheads as well . Calaveras may be eaten , or kept for a few days and then thrown away .
