Oaxacan street art has reached global audiences through the work of Lapiztola, a small collective whose startling murals are usually based on photographically real images with creative embellishments and a strong political message. Their work has appeared or been exhibited from Stockholm to London to Sao Paulo to the USA.
Like all street art, Lapiztola's work is, by its very nature, ephemeral. Their highly topical etchings come and go. Check out their Tumblr link and see what you can track down.
