Guess the flags of the 31 states and one federal district of Mexico.
Most Mexican states do not have an official flag. For these states, a de facto flag is used for civil and state purposes, typically consisting of a white background charged with the state's coat of arms.
Baja California and Campeche have provisions in their constitutions explicitly declaring that there shall be no official state flag. Their de facto flags are included in this quiz.
Some coats of arms contain the state's name, and thus the answer is in the flag.
