Hi Sue
Thank you, and yes I remember the symposium well although it's a few years ago now! If you remember , I started the paperweight section of the talk, speaking about John Ford paperweights. I gave a subset of the talk to the NPS a couple of years later and amazingly one of the members had a John Ford paperweight and brought it to the meeting, talk about nonplussed! First and last time I have ever handled one.
Best regards
Derek
