"It has been brought to our attention that a company trading as Expo-Guide is claiming to be publishing a guide for the fair and they may contact you to sell advertising," say Clarion.
"Please note, this company is NOT the official publisher and you are advised to ignore their correspondence. Expo-Guide has no connection with Clarion Events and their guide will not be distributed at the fair."
ATG have seen copies of the forms sent out by Expo-Guide, giving a Mexico-based address, under the title Exhibitors Directory for Fairs and Exhibitions, which ask recipients to confirm the accuracy of details listed.
However, in the small print just above the signature strip lies the true purpose of the exercise, an order for expensive and useless advertising.
It is accompanied by the usual caveats on cancelling orders so as not to incur further charges down the line, as well as reserving the right to take legal action in cases of non-payment.
