Hello is this Nirvana signed cd real ?I would love to own a REAL Nirvana and want to know if any experts can tell me if it is real ??

Ebay seller sweetsoulsister2019  is who sold it .

I found 4 signed Nirvana cd's he sold for a 800-1000 in his completed sales .

It seems very suspicious .PLEASE let me know what you guys think .

Also if this seller sweetsoulsister2019 is legitimate or a forger .

He states that the Nirvana's will pass a forensic document examiner  .

Here are the 4 item numbers of these Nirvana 's 

18404002606

184013215406

184003264024

If these are real 800 to a grand is a steal for these .
