The pre-Colombian collection was not so impressive, but it was a good educational foundation for those who don't know anything about Mexican history, which I suppose is the point. And to be fair I recently visited Chichen Itza in the Yucatan and it doesn't seem that anything will ever compare.
One of thes special exhibits however is one that I know very well as a historian of Latin America and Latinas in the US. Rastros Cronicas: Women of Juarez is an exhibit chronicling the crimes against women in the factory town on the border of Mexico and the US. Here I was allowed to take as many photos as I wanted. I was truly inspired by the artists' interpretations. Flash wasn't allowed, but I got some good shots. This is a collage of the photos of that exhibit created in Picasa.
