I know it’s old, but I still allow myself to wonder what poor old Bill Posters did to deserve prosecution. Not only that, but to have notification of his fate emblazoned over walls, telegraph poles and hoardings! As a kid, I really did want to know who this mystery Bill Posters was—and my mother, with her unalloyed delight in wordplay, did nothing to dissuade me of my misconception. Years later, the caution is still being publicised, and although I now know what it means, it’s still good to see that Bill Posters will be vindicated.
