So you got it from Amazon, right? Congratulations on that buy! You can check out all the signatures on these pages, there are letters, numbers and sigils. Regarding the second part of the signatures, I think that "mory-7" is "Morisette" -- in French "7" is sept which sounds like "sette." Jim St Denis & Olivier Morissette are almost certainly french names, right?

And of course I'd like to see the follow up!
