Alas, probably not. I live in the Dominican Republic without reliable/affordable access to mail, so I can’t easily receive a book from you, sign it, and return it. And I really can’t receive/return whole cartons of books from my various publishers’ offices—which means that if I ever sign a large quantity of books it’s because I happened to be in New York or London and they were needed for a specific event or account. So you probably won’t just find one on a shelf someday, but the good news is that if you do, it’s definitely rare and precious. Congrats!
