Great action from Brazil done by a group of friends called Mudanca.
They want people to bike instead of driving a car. It is cleaner as they sweep.
The stencilled text: “Bike não suja tanto” which means “Cycling isn’t this dirty”.
How can we name this urban intervention? Dirty finger stencil activism?
