GUEST: In 1987, when it was published, a friend of mine showed this to me, and I fell in love with the artwork. It was, I think, $90 at the time, in 1987, and I couldn't afford it, so I found this at a flea market.

APRPAISER: What did you pay for it?

GUEST: $50.

APPRAISER: Paul Grushkin is the author of the book.

GUEST: Yes.

APPRAISER: And it's a pretty common book. But you kind of did something pretty extraordinary with your copy, in that you took it with you to so many concerts, and have 242 signatures in here.

GUEST: Yes.

APPRAISER: I went through the list that you gave me, and the list is long. Everyone from Willie Nelson to Joan Baez. We have a giant Steve Miller down here. I was particularly interested with your Ginger Baker, because he's such a prickly character that he gets a bad reputation. How was he when you met him?

GUEST: He was very nice. We met him at a... At a show in Oakland. Uh, a jazz club called Yoshi's, and, uh, we got to go backstage for just a few minutes and meet him.

APPRAISER: In addition to that, you have Victor Moscoso, Stanley Mouse, Chet Helms-- some of the guys who were really instrumental in creating the artwork of the '60s and the posters that we all know and love from those shows at the Fillmore East, and all over the country. And Stanley Mouse even added this drawing.

GUEST: His alter ego. These artists all charge for their signature now, and he gladly does something like this.

APPRAISER: The book itself, it was kind of the seminal work that documented all of the posters of this era. A copy of this book, a first edition, in great condition, is worth $100 to $150. Yours is not in great condition. Something like this-- how did this damage occur?

GUEST: We met Bo Diddley at a local county fair and, uh, took some things back to have him sign, and he had a bunch of rings on his finger, and the ring cut the book.

APPRAISER: So it's celebrity damage.

GUEST: (chuckling): Yes.

APPRAISER: Because of the fact that you have these 242 signatures, plus all of these drawings, and all the stories, because you met some really fantastic people, at auction, I would put an estimate around $2,000 to $3,000 on the book.

GUEST: Okay. It was a labor of love. We took this to every concert we've been to for the last 25 years.
