"Paul, I ended up buying the one I posted pictures of here (cost was around $250). The signatures appear to be fully authentic, as they also appear to be signed by three unique hands. The autographs are spot-on for the 1994 time period as well."
"A real authenticator would know your signature is legitimate. Although I own several sets of Nirvana autographs, I'm jealous. I'd say hang onto it (sorry, Paul!). It's worth a few thousand for certain, however. Thanks for sharing."
