Is this a missing piece to Jodorowsky's Dune?

Grady Runyon owns a used record store in Ventura, CA. In this video by Rossangeles, Runyon tells a wonderful story about how a stranger asked to meet him in a parking garage to show him a mysterious artifact: an illustrated handbound manuscript with the title "Screenplay by Alexandro JODOROWSKY / Adapted from " DUNE" / by frank HERBERT."

The color pencil drawings in the book are highly detailed outsider art scenes of weird sex, monsters, outlandish costumes, and exotic weapons. When Jodorowsky caught wind of the book, he tweeted that the artifact was a "fake script with idiotic drawings." The book sold for over $6,000 when it was auctioned on eBay. I'm not doubting Jodorowsky -- the manuscript could very well be fake. I think the illustrations are wonderful, however. Again, I'm not arguing with Jodorowsky -- I'm an idiot!
