I have had several offers already on this item through e-mails, i will only sell this item via the auction, thanks.
All e-mails will be answered.

All the details, as far as I can tell, seem right. But is it REALLY real? (And what is a “genuine copy” when it is also described as an “original”?)

I’d be curious to know how this precious item came to be on the open market. Who would have had it before? Who would want to get rid of it? Shouldn’t a certificate like this be in the possession of Bon’s family? Any ideas?
