well, the Ash head is amongst the previously released continuity polaroids. Well at least the six limbed alien sketch is new or at least it's a piece of Alien Resurrection concept art sketch that ADI didn't release recently.
Looks as if more than one seller are making claims about it having a Giger interview
Unless someone can say he wasn't interviewed for this I suppose Giger could have been interviewed in the last year before his death or they found an old unpublished interview,.
well, some sort of photo from the blu-ray or DVD set rather than specifically continuity polaroids.
