The twin brothers Otavio and Gustavo Pandolfo - aka Os Gêmeos - from São Paulo are the major representatives of street art in Brasil. First influenced by American hip hop culture as well as national pixação movement, their graffiti usually feature yellow skinned characters, colorful subjects and strict reference to Brasilian topicality and culture. Their spray-painted huge walls are today standing not only in Brasil, but also in USA, Netherlands, Lisbon and many other countries.
