I appreciate the suggestion! However, I have already been in direct contact with Leif and I got all the pages that he had. John Stokes got half the pages and these seem to be "out in the wild".
A year ago I thought I hit a jackpot when I saw the pages that I need on "Artist's Choice" website (which represents John Stokes), but it turned out that the pages got sold a while back and the website never got updated. So, the pages were purchased in the last few years and they are out there...somewhere...
I do appreciate any and all suggestions! Please keep them coming!
