Apparently, if you want to discuss the advertising campaign you call Kieran Palmer on 01277 252355.

Calling the number on the posters will get you some unfortunate person who knows nothing about policy, so please don't - unless you want to make a polite request for a brochure to be sent somewhere interesting.

All these photos are anonymous and still 1998
