Yes, I think it does. It is more "art" and less "personal statement".
No special meaing that I'm aware of. But yes this is quite typical. In downtown Sofia almost every building on these side streets is covered in 'street art' or 'graffiti' depending on your point of view - or a combination of both. There are also sponsored street art events every year where artists from Bulgaria and farther afield are let loose on a wall somewhere. A few years back they covered all the electrical boxes with street art as well. Some of it is very creative, some of it is just ugly. As for re-opening, no time soon, I think. In the meantime here are a couple of other examples.What an extraordinary piece of street art! Is this typical of Sofia? How soon will you re-open to visitors? Does "chump" have a meaning in Sofia?
That's beautiful artwork for a neglected street. Can you show us some context shots? How do these fit in on the street?
