this stance is evidenced by the 'não pixe, grafite' (don't tag, graffiti) project put on by the city of rio in 1999 to showcase the styles of 35 local non-tag artists.

graffiti has become one of the most cost-effective ways to rehabilitate walls and other public spaces.

for this reason, it has become fairly common for graffiti artists to be commissioned by the government to recuperate an aging or underutilized area.

in 2014 the institute eixorio commissioned 130 artists to paint a  40-kilometers wall edging rio's subway line 2, from são cristóvão to pavuna, creating the biggest open-air art gallery in the world - named galerio.
