Posters, posters, posters everywhere

All my life, at least since I am 16 year old, I was organizing events, and part of this was advertising them. We usually did that with posters. But we always followed one rule: Ask before you stick a poster on someones property. When We were not able to ask, because we did'nt know the owner, we built our own stand, and, with permission of the community, placed them next to the street. In Laos, you see more and more posters stickes on fences of constructions site, on phone company boxes, lantern masts, everywhere. I was told police was already complaining. What is really sad, is that foreigners who should know better how dirty a city looks like when everyone uses everything as advertising space, are the ones who pollute a lot. See the picture I took opposite True Coffee. I can't believe there is a lack of legal places to advertise.
