Well, I'm still waiting for answers to my last two trivia questions — one's quite difficult; the other one requires a westlaw search. Whatever — I know people are busy these days.
Let me try another one that's pretty difficult, but maybe not impossible (or maybe rather easy if you look at the picture closely!). A great antiquarian bookstore is in this building. I've been buying from them via the net for years, but about a year ago I had the chance to visit them in person. Where is it? What bookseller is in the building?
Oak knoll Books store in DE.
You got it exactly, Joan. Oak Knoll is in an old opera house in New Castle. Long-time readers may recall that I've posted before about New Castle, including the William Penn statue there:
