The aim is to cover the 40.4 kilometers of wall that constitute Line 2 of the metrô (subway) with panels drawn by more than 130 graffiti artists, divided into 13 groups of 10 artists.

The project is led by renowned artists such as Acme, Airá OCrespo, Anarkia, Afa, Akuma, Bobi, Dante, Davi, Duim and Meton.

Inspiration for the panels will largely be taken from issues, stories and figures from surrounding neighborhoods.

In the district of inhaúma, the artists will portray scenarios relating to the Escola Municipal Barão de Macahubas (the Municipal School of Baron Macahubas), a school attended by generations of families.
