Whilst
Brazil won the graffiti award I think the best stencils I have seen have been in Buenos Aires. It is such a political place where people are passionate enough to protest. Since Evita made her speech in the
Plaza de Mayo has become a constant place for people to voice their opinions.
Here are just a couple of cool stencils you can find all over BA.
If you life a good stencil here is a good
blog.
