If that would exist, people would pay THOUSANDS of dollars for it! There was a set of photographs of all pages sold by the propstore and also this pictures set sold for a few thousand dollars. The pictures in the diary came from "source books" in many cases. On the Club Obi Wan forum, you can find info about these source books and also scans of these drawings. But what you are asking: a PDF of the original grail diary pages, does not exist.
