I was talking at length to the framer when I picked it up. He too just loved it. Full of Wow's and other suitable epithets.
But then we were talking about the design and the rarity of this design and format as opposed to the variously coloured panelled formats. For saying this poster was to advertise a spy / action / exotic film, the design is truly understated.
And I offered that this is perhaps why this poster is so rare... Maybe it wasn't selling the deal and focus was placed on the, today, better known variants.
All supposition of course. If anyone has knowledge to offer, would be happy to hear.
