When I first looked at the picture and saw two copies of "You Only Live Twice" I thought, "Ha, ha! How clever!" Then I saw you have two of "Mooraker" too.
Paperbacks can get spendy. A couple of years ago I wanted a copy of "Street Rod" by Henry Gregor Felsen. I read it as a kid. (It was supposed to be a cautionary tale for teenage gearheads but I saw it as a roadmap for my future.) Anyhow, ratty copies were going for $30-$40!!
