Remember - the rare unsigned ones may be the better long term investment...
That is correct in the majority of cases.
I'd be happy to
settle for a 'reduced investment' version with your signature on it; to my mind that makes the book all the more special.
Definitely one I'll be adding to my book shelf and I wish you every success with it Peter.
If you'd like to post a link to the book page in the For Sale section, I'd be happy to approve it.
