I can only draw as a show promoter who wishes to set up at a show.
But, we've discussed this in the past --- the old concept of the pre-1980 show would be kind of cool where everything displayed would be before 1980. (you could sell more modern stuff too, but the display would have to be vintage)
I think we could get Roger N. on the right weekend and a few other vendors (including yourself) but the show would have to be a weekend show and expect a slower attendance but a lot of camaderie.
One day we'll do lunch and discuss this further. May have to be on a weeken though
