Well, she went for $810 to a map dealer in London, and he had to pay about another $200 for the eBay global shipping program and duties.
I asked one of the other losing bidders about what I had here and why it was popular... he said "Dealers are collecting them and trying to sell them at various price points. So far sales have been pretty minimal at anything over $1000. The exception is that some libraries are starting to collect them with an eye on the future." I'll see if I can stitch a good scan before I ship it out. - John
