I attended a couple back in the middle 80s or a bit later, at the Infamous George Washington Motor Lodge, in Willow Grove. The huge lines, the crammed hall, and the amazing stuff. Great memories. I remember meeting Chris Short in line once, having a chat. I had no clue who he was, t hen he told me, and it was an honor, and what a nice man.
I got a lot of nice things in those days, I also recall an incident where Al Rosen had some unopened grocery racks from the early 60s for sale, the 3cellos in a sleeve, and someone accused him of having fakes. Nearly a fistfight broke out too. ha.
Other things I recall bout that place: It was the first time I ever saw a real T 206 Wagner, and also saw the most T cards I had ever seen, from my Wayne Miller. Also, dealers like Brian Morris, Paul Lewicki, and others were great stuff.
PLus, I was able to make the four hour plus drive on an hours sleep down there. To be young again....
