As a dealer for 35 years I feel I must reply to the private collector who feels hard done by because some fairs have a trade day (‘Trade day at a fair is unfair to collectors’, Letters, ATG No 2541). In my experience very few fairs do this.
Most fairs charge a higher entry fee for the privilege of entering with the stall holders (IACF £55 early entry) and this is open to anyone, private or trade. If private collectors want to get to the fair at the crack of dawn and gain entry with the trade they are free to do so.
I’ve never known anyone refused entry if they are willing to pay.
