Here is a picture of Nuevo Espana (Mexico) in the year 1650. What is helpful is the names of the different sections such as:
"Reino De La Nuevo Galicia" "Reino De La Nuevo Viscaya"
"Nuevo Reino De Leon" "Reino De La Nuevo Espana"
This is interesting as when I had been browsing through the baptism records and saw those names mentioned above and now know what it refers to:

Also came across this drawing of what Teuchitlan, Jalisco may have looked like during Pre-Colombian times. Interesting:
