As I was walking along Great Portland Street this morning, I noticed a very grubby water van. As, it seems, had someone else:
They’ve wiped the dirt off her teeth so they stand out, and if you can’t read it, written: “Teeth need whitening? Dental Centre: 02074377140”. (Beside that, someone else has written “Just brush them and save money”).
An eye-catching ambient idea that cost nothing. Love it.
