I must apologise for the poor quality of this image. I snapped it last night, and it looks like I did it by candlelight. So you'll have to puzzle over it very carefully. I note that the number plate says the car was apparently registered in the North Riding of Yorkshire, but I wouldn't mind betting the letters are the artist's initials. When I worked in what was then called 'commercial art' we were always doing things like that. Hiding questionable details in silhouettes of trees or clouds, putting spurious headlines on newsvendor's placards and our girlfriend's or wives' names above shop fronts. Sometimes both.
