re: #111 jaunte
I have Niven’s Laws, a hardcover I picked up at a convention in the 80’s, and had thought was rare. It’s $80 at collector sites, but I could get another copy in collectable condition for $24 via Amazon.
My most prized possession is a bootleg Dalek Master Plan book I printed back when I worked as a pressman in a print shop and ran a Doctor Who fan club, that’s signed by Nick Courtney. He made his first Doctor Who appearance in that episode as another character before he was cast as Lethbridge-Stewart.
I doubt that a dozen copies of the book still exist, and with the autograph, It’s one of a kind.
