Here's a random mural on a random corner. I can't quite make out the words.
This is not actually on a wall, but rather hanging from a wall, to be precise. It's some sort of strange iron work that surrounds a small structure within an old factory that's been made into an arts center in a town called St. Agustin Etla. I'm just not going to speculate about what's going on here.
And some political artwork -- "Her future is in your hands. No to the privatization of education!!"
