The seller initially said this autograph would pass PSA DNA. Well, I paid for it and it didn't. Then I got this response after I said it didn't pass:
"They are entitled to their opinion, it's hard to try to argue with PSA/DNA because they are basically monopolizing the autograph industry and in all honesty they make mistakes.The only 100% way to be sure is if you were there.Don't worry I will sell it to a true connoisseur because this is real."
Spoken like a true ignorant seller who is unable to stand by their own words. Thankfully this person is not a dealer.
Just to clarify, I did not purchase this Kurt Cobain autograph. I paid for a quick opinion, not for the actual autograph that was for sale. This example came from the ioffer website, not ebay.
