One of my favorite spots is right around the corner. Here is my piece in an inaccessible backyard at the Hamburg subway U3.
It smells of paint and petrol. Mostly I work from car roofs and bonnets of carts waiting for their slaughter. The flair is unique dirty and makes the place so authentic.
I can paint my pieces here undisturbed, without anyone crossing my way at this inaccessible place. The train rushes by behind me on the high road. And it's only visible to those who pass by with the train.
