Deletion of Harryhausen: The Lost Movies

Comment: promotional material about a book that has not been published - the references are promotions for an unpublished book - the article creator has made few edits outside of John Walsh and Harryhausen - the John Walsh article has been up for deletion and there is a note on the John Walsh article that "A major contributor to this article appears to have a close connection with its subject" (same article creatory) so there may be  and sockpuppet issues here - maybe after the book has been published and has multiple significant reviews or writeups in reliable sources the article can be recreated - ( says we shouldn't have articles about unmade films, but this is a book about unmade films, so not sure if that guideline applies
