México, 1821

Here is a cool map of Mexico from 1821. I like that it shows the different states/territories. I have a book on Mexican history headed my way via U.S. Mail, I am interested to see when the current state's borders were created. I am also casually looking for maps/city plans of Mexico City that predate the 20th century. I may have to go to Mexico to find anything with a good amount of detail. This isn't really related to my dissertation, I've just always loved maps and seeing how borders and place-names change over time.
