This photo was taken at a museum in Guatemala City. The featured mask (with costume) is for the Deer Dance. The ones on the wall come from different dances. Shops will rent masks and costumes to the locals for an affordable price. They’re called morerias.
This small country takes masquerade very seriously. There are many unique masks for tourists and collectors to enjoy. In my book, Masks of the World, I devote a whole chapter to this special part of the world.
