Those of you who teach Mexican Folk Art will want to take a look at
this exhibit (it is all folk art).
Tesoros Escondidos: Hidden Treasures from the Mexican Collections.

Since this is a temporary exhibit - I would check now for images.

scroll down... You will see they also have a Teaching Kit available
(lucky for list members within driving distrance to this museum).
