Don't Shit in Buenos Aires

We are a group of creatives working in different agencies who anonymously gather in a project called Tu Plata No Vale (The translation would be something along the lines 'Your money is no good here') and we work for free, creating guerrilla campaigns for social causes. In these case, to put a stop to people that leave their dog's poop in the street. It's a very simple idea: we put a little flag with a claim that reads 'Don't Shit in Buenos Aires' on every poop we find on the street. The campaign has just launched, and it's already creating a little buzz.
