There are signs with values all over Oaxaca, on highway overpasses, on shoeshine stands, and billboards on walls in town. They have a word: patriotism or self-esteem or, as this one in Huyapam: humility.
With each of the words or phrases, there is a brief definition that is part education and part friendly reminder of one’s responsibility.
As a Spanish student, I find them helpful. I wonder though if there is a better way to “advertise” these values, or, perhaps more importantly if Oaxacans need these reminders.
