I've been waiting for some time for it to arrive, and there it was today, propped against my door when I arrived home. I nearly wept for joy. I can't tell you what it is yet, only that it is something wonderful.
Oh, you might try to guess -- a page from a long lost Leonardo Da Vinci notebook? An original copy of the Declaration of Independence? Nude pictures of Bea Arthur?
Trust me, try as you might, you'll never guess what sort of magnificent thing is inside the package. You'll just have to be patient and watch this space for further details.
