The exhibition proposed is titled Break the Trance, will gather an array of visual materials designed by Adbusters. 
 
The exhibition will display artworks, posters, spoofs ads and cover magazines that chart climate change, economic and environmental issues, just to name a few topics.  

Regarding the amount of materials it will be according to the available exhibition space. The display might collect 15 posters (50 cm x 70 cm), 20 magazine’s cover (20 cm x 30 cm), 5 large posters (110 cm x 70 cm), a cloth banner (11300 x 150mm) — with the title of the show — and around 2000 stickers to freely be given away to the visitors.

All the Exhibition Materials has to be produced. 
They can be printed in Sao Paulo, as Pedro Inoue, Adbusters creative director’s, is based in Sao Paulo (Brazil), so he can easily follow the production process.  It will be interesting to have an intervention by him in the exhibition space. He could draw with spray-paint on the posters and in the exhibition space.

I’m attaching in the following step a visual display of Adbusters' previous exhibitions held in Korea, and some posters, so you can have a clearer idea of how it could look like. 

If you plan to select a Brazilian location for this show, Inoue could help you during the set up of the show. I would love to come over for the setting as well, but as I live in Milan (Italy), I’m not sure if I will be able to come to South America due to the current COVID-19 restrictions.
