i admire what you do and the community obviously needs you, but I also want to let you know, that I would rip off your posters from the wall next to my intercom or from the antique entrance door to my flat without even reading what they say. And I would feel good about it.
post soviet countries which had to adopt capitalism very quickly suffer under omnipresent visual ugliness. there are many reasons for that, but in my opinion, your posters don’t make it better. they are just the way things are.
but, especially in the European Capital of Culture, there are so many people who don’t want things the way they are. they want change. i’m sure you will reach them.
edit: but still, if the posters get people on board, they are probably worth it.
