Shoes on a wire

This sight meets my eyes every time I look out the window. A pair of old school Nike's from the 80's hanging on a telephone wire. Apparently it's a common drug dealers mark and means that there's a drug dealer living in the building. I know our next door neighbours pretty well and can assure you that they're not drug dealers. And anyway the shoes are hanging directly outside OUR window so I can only assume that there was a drug dealer living in our flat sometime during the 1980's-90's.

And here's some artwork I see on my way to the super market
