I’ve always been a fan of the street artist El Tono, and his ability to adjusts and morph his simple geometric line patterns to the different social contexts he works in. He’s the master of making street art that operates as folk art, and folk art that operates as street art. He was recently in Peru and Brazil, making posters and painting buildings. In Peru her worked with Equipo Plastico, making posters based on the “Chicha” style of street postering. Here’s a cool image, and more can be found HERE and HERE.
While in Sao Paulo he painted a building with Nuria, and there are a bunch of great photos of it HERE.
