First of all, sorry if this is not the right forum. Wasn't sure where to post. I'm new here.
Anyway, looking for a bit of advice. I'm looking for a recommendations finding a service that would be able to authenticate my signed vinyl copy of Rattle & Hum. It came into my possession when I was 16 years old or so, and I was organizing small rock concerts for high school bands in Dublin, where I grew up. I've had it for years but I'd like to sell it now.
quoting "Unless you were there when an autograph was signed, you really have no guarantee -- not even the ever-present "Certificate of Authenticity" -- that the autograph you're buying or trading for is legitimate."
