A font based on the city of Sao Paulo where the municipality introduced the ‘Clean City Law’ in 2005. The law forbids to display advertisements in public space. Not only does the municipality create laws such as ‘The Clean City Law’ but is also perceiving other goals to keep the city ‘green’. The city itself is a kind of recycling machine, for example the catadores whom collect rubbish in order to exchange it for money. I reacted to this idea and created a font that has a reusable value. Each poster can be folded to seven different kind of font characters.
