It was removed from the article a while ago, and for perfectly valid reasons.  Since then it has been orphaned, and was subsequently deleted as all orphaned non-free images must be.  In short, while you can ask an admin for undeletion, you really shouldn't.  The image does not appear to be needed.  Meanwhile, you should concentrate on adding a fair use rationale to Image:Cover-th-warrant-for-genocide-1897959257.jpg, which is currently missing one and will be put up for deletion if such a rationale is not added.
