About the twin brothers Os Gêmeos

'Os Gêmeos' are twin brazilian brothers called Otávio and Gustavo. Searching on Wikipedia, we can discover that they started painting graffiti in 1987, so that's a long time - they are very sucessful artists outside of the country. Their most important work is to paint the facade of Tate Modern (an important museum in London), and to expose their work inside of the museum, sharing the space with other graffit artists. Their paintings, in Brazil, are specially concentrated in São Paulo. Their paintings show yellow-skinned and poor people at most of the time. Some of their work:

Graffiti at Houston Street, New York

Painted train in São Paulo

Tate Modern, London

Kelbum Castle, Scotland
