When the election times arrives in Brazil, all cities turn into a mess with candidates advertising material thrown everywhere. The "cavaletes" were the worst of all, because they didn't respect the laws, standing in sidewalks, ruining public gardens making everyone pissed with all the politicians.
Use the law to fight the abuses. With the brazilian constitution under our arms we invited people to:
1- If you find a Cavalete disrespecting the law remove it and take it home
2- Make your art.
3- Bring your cavalete to the exhibition
