Have you heard of this PDF of The Jungle Book

Does anybody in this group you host ever heard of this PDF. The Jungle Book original draft or something like that? Which https://www.deviantart.com/mowglithelostmancub told me about because I mentioned on when Jon Favreau's sequel to The Jungle Book comes soon, that Bill Peet's early draft might get released. Since Jon said he's using plot elements from this unused draft in order to make this film. It's said that the PDF script would be also be dated a year or more before the film? I did try to look it up, but I can't find it, especially since some were see downloadable and I don't want to risk getting viruses on my computer.
