Q: This nice little mask seems similar to the coconut masks made by Nahua Indians in Guerrero, Mexico, but it's less brightly colored, more detailed, and appears older. Kay, 1-10-12, 266
A:
I think you've got it right. These coconut masks have been
popular tourist items all along the SW coast of Mexico, not just
Guerrero, for many years. Some of the oceanic cultures make them
as well. In Puerto Rico they use the larger husk for masks.
