Calavera means "skull" in Spanish, and is a type of traditional Mexican ornament or treat used on the Dia de Los Muertos ("Day of the Dead"). Traditionally they are made of sugar, but as you can see from this gallery the variety is enormous. Downloading of these images for any purpose without Amoxtli's explicit written consent is prohibited and violators will bring the curse of the Calavera down on themselves. So, don't say you weren't warned...
