That is an insanely low price for this miniature in my opinion!. Such an iconic & intricately built model. I would have thought the Alien franchise & in particular the Nostromo would fetch something like $2m.
It is absolutely huge!! Part of the value of an item is linked to one's ability to resell it and IMO alot of people who are huge Alien fans AND may have the discretionary income to make this purchase- may shy away because of it's sheer size and needing it's own room essentially to adequately display it!! Amazing restoration job!!
