The sign on the leftis from ISO3864 and BS5378. It is internationally recognised and has been carefully designed and reviewed to ensure clarity and comprehension. It has been around for over 25 years.
The sign on the right is the New and Legally Required sign that all buildings in England must display from Sunday onwards (including Grade 1 Listed churches and cathedrals).
Now, you mught say "what's wrong with the new sign?". Well, on the face of it not a lot. But why has it been felt necessary to create a new sign? What was wrong with the old one? And why is it necessary for anyone displaying the current, internationally recognised sign, to remove them and replace them with the new Tony Blair recognised sign?
Incidentally, I'm not sure that I understand why smoking is the only offence that it is necessary to warn against. Where are the signs saying "No killing: it is against then law" or "No glorifying terrorism or terrorists"?
As usual, suitable comment at the Cartoon Church
