Interesting thread.
Mel, mind if I add those Blade Runner pics to our site for reference?
and just to clarify:
We had one consignor with hundreds of ROLLED one sheets and half sheets who worked at Continental litho during the 70's to early 80s.
We had ANOTHER consignor who was a studio executive from 1968-72 that had access to an nss facility where he pulled out ROLLED one sheets and kept them each time he visited.
We have had two consignors who used to work at Gore Graphics that had lots of rolled Printer's Proofs from the 70's and 80's.
and......starting in our eBay NO RESERVE auctions this Thursday we have a folded NM-M C9-C10 Blade Runner one sheet.
