are (usually) illegally erect
s on walls
, bus stop
and other handy objects. The illegality of the practice does not stop it being incredibly commonplace (in british

in your local city.
I have seen walls with layers of flyposters literally inches thick; if excavated, they would be like a record of the underground music scene of leeds (where i live) over the last ten years.
