I read with interest your news highlighting the decisions being taken by several fair organisers to make changes to their admissions policy (‘Fairs tickets are going digital’, News, ATG No 2541).
For many years collectors have received complimentary invitations to fairs, digitally or otherwise. The collector will most likely have received a personal invitation from an exhibitor or organiser, or voluntarily downloaded a ticket from a website.
This is standard practice to ensure collectors are encouraged to attend an event.
