Axe painted the wall of the MAAP with 2 drawings: on one side a face, on the other a child who makes soap bubbles and the phrase "I don't want your hope", quoted by the environmentalist activist Greta Thumberg.
This work was realized for the Biennale street art "Superwalls" (June 2019).

For the biennial murals, the artists used paints that, activated by light, purify the air purifying it from pollutants.
