Sao Paulo is the largest city in the country of Brazil and is home to a lush collection of public "street art" graffiti. Pixação, originally pioneered in Sao Paulo is a form of graffiti that is most notable stating back to the early 1940's and 50's using tar to write messages on public buildings that captioned usually rebellious statements against the government. Turned from a political to a social expression It is now the term used when describing the "tagging" style of graffiti which is still illegal in Sao Paulo. With a dark but honest past, graffiti in Sao Paulo has taken a new path in how it can be an empowering form of artwork. In 2008, the city of Sao Paulo declared "Graffiti" legal in a law passed that separates the contemporary approach from its tarnished past. Underlined with a building owner's consent, Sao Paulo's graffiti artists are able to explore an entirely new world of graffiti that allows for deeper expression and more polished pieces of work. A lot of the graffiti in Sao Paulo today is done by designers, muralists, and other professional artists but the most enriching partakers in the new wave are former practitioners of Pixação. The evidence of this shift in the Sao Paulo graffiti movement is its recent murals done in the last few years captured in this on-line exhibition that showcase a new message of hope, freedom, and equality among citizens, and artists alike for the years to come.
