I love this thread! I cherish my Stevie colllection. I've never seen the Buckingham Nicks album signed by both of them.
What eludes me is getting Stevie to sign my Rumours album. I'm extremely grateful that she signed the IYD litho at Amoeba this year, but I wish I had not followed rules like other people and sneaked Rumours in for her to sign!
That record has been signed by Mick and Herbie, so someday I hope to have Stevie sign it.
Best of luck with your auction.
