Warning from CLEO Show Management of potential “poachers”

CLEO Show Management does not release its exhibitor contact list to anyone except official show vendors. If you are contacted by any vendors, always ask them to send you details in writing, and look for the Official CLEO Vendor Seal on any written correspondence. If you are contacted by a non-official vendor, or are unsure, please provide us with the details regarding these calls or emails. We will follow up aggressively with them.
