Reverse Graffiti — São Paulo
A growing number of street artists around the world have taken to expressing themselves not with spray paint, but with cleaning solvent. The practice known as ‘reverse graffiti’ has been popularised by the British artist Paul Curtis, better known as ‘Moose’. Brazilian Alexandre Orion temporarily turned São Paulo’s Max Feffer tunnel into a 160-metre-long mural of skulls using only a damp cloth to clean away the dirt on the walls. The police intervened but, realising that Orion’s activity basically amounted to cleaning, let him go. The authorities would later erase his selective erasure, thus effectively cleaning the whole tunnel.
