I like just about everything about this. The black and white checkers along the top look like part of a film strip, like it's a small clip from a road movie. The dots on the arrow and letters are 'cats eyes' so they reflect the headlights. I can imagine the driver of an Austin 7 squinting through his rain soaked windscreen at the faint shine of the numbers. I don't often wish this, but I hope it's listed.
