The Calavera de Azucar or Sugar Skull was born from the Mexican Day of the Dead. In celebration of the dead, altars are created in remembrance of those who have past. They are decorate with marigolds, sugar skulls (literally edible skulls made of sugar) and other finery's. Now a days sugar skulls are iconic in tattoo art, sadly mostly amongst hipsters.
