Human mask carved from a light weight wood and covered with tiny pieces of turquoise and black stone. The mouth is slightly open, revealing a row of upper teeth made from white shell. The eyes are made of mother-of-pearl, the pupils of which are indicated by circular holes cut through the shell. A small hole drilled through the right temple allowed for tying on the mask (the left edge of the mask does not survive).

Masks imparted identity to bundled funerary remains and to living performers taking the guise of other beings. This rare example of a wooden mask originally was covered with an intricate mosaic of colored stones and of turquoise, imported from northern Mexico or New Mexico.
