Originally we were at a loss to explain what this meant!
But this little
note, in John's handwriting, has generated a surprisingly large amount
of interest from fans. We now think that the explanation for John's message
'Fold Nine Times' is in response to the question whether a piece of paper
can be folded nine times. It is generally agreed that it cannot, whatever
its size ... a claim contradicted by the Stanford University website.
What we can probably agree is that a piece of paper this size cannot
be folded nine times. No doubt the debate will continue!
