Well it’s not quite a Banksy...

... but I suppose it brightens up a tumbledown old shed.
This is on a path leading to one of secondary schools in the island and the only prison. This part of the path was created by Guernsey Living Streets so that school pupils had safe access to walk or cycle to school from St Peter Port. It’s also pretty sheltered while the alternate for many would be the road along the sea front. I don’t know how much it is used though.
I was here to grab a cache which is between the school and the prison.
