This superb map graffiti came to us from Topi Tjukanov via Mark Safran, thanks to both of you.
“I always admire this graffiti when I walk past it. Today with the sun shining it looked exceptionally good.
It’s located in Suvilahti, Helsinki and the graffiti was created by Finnish graffiti artist EGS.
