It's not something that would ever be considered an exemplar of a genuine MJ or have any value in my opinion, but the M and N are close enough to me that I think it's in the realm of possibility.
No offense taken. It's not for sale so there is nothing for me to prove. I agree the signature is not the best but like I said, I was there so I know it's the real deal. I have other items from that night (tickets, sticker VIP badge) but even that doesn't prove authenticity either. So again not offended, just trying to show something different to help out.
True can be stranger than fiction. I believe your story and if you intent is to keep this item, all the better. But, if or when it comes time to sell that's a different story. It always comes down to the opinion of the buyer and what they would be willing to pay for it. But the memory has a value no one can buy.
