I realize Pittsburgh PA is the one most likely to be available, so am hoping to hear about the other towns. I have, though, ordered catalogs from PSS, and after they arrive will be able to be more specific about items from Pittsburgh that are particularly of interest — although any with included initials/dates will definitely be on that list.

Thanks for looking!
