Not finished

I went for a walk in the Mauerpark (https://www.berlin.de/en/parks-and-gardens/3561684-4407152-mauerpark.en.html). It was bizarre, walking one way in alongside everyone bbq-ing with the associated smells, and then back next to the wall with active graffiti artists and the smell of spray cans.
The artist from my extra photo shouted at me that it wasn’t finished and so I shouldn’t take the photo, but I told him that was why I was taking it, because the “nicht fertig” was amusing….
