An otherwise prosaic kerbside advisory sign in Hopetoun Street has an unofficial addition.
The slightly jaundiced expression of the subject suggests that he is no more impressed or excited by residents' parking permits than the rest of us.
But who is he? Where is he from? And what was the artist's original intention?
Since Spurtle began featuring curious street-art on Broughton's streets, and requesting more information from the creatives responsible, we have never got anywhere.
If you need to know, it seems, you are most unlikely to find out.
Still, we live in hope. Can any reader help?
