One of my most favoritest things about my favoritest places is the incredible political graffitti that starts to speckle the walls after many years of chaos... (addendum: i have been chastised and called elitist for not translating these. It's nice to know people care. Translations added, thanks Uncle Pime!)
"Revolution in the plaza, at home and in bed."
"It's the Vatican's fault."
"Are we really in a democracy?"
"The pencils keep on writing..."
"Victory for the Palestinian resistence"
"Where are the Disappeared?" (This building contains military history; the question was not randomly placed!)
"Revolutionizing memory, constructing the future."
