Thanks, Rich. That one has actually been bugging me for a while as I think that much of John's work. He's the best in my opinion right up there with Dario. So I wanted to know "what the deal was" once and for all.
So you're saying, ultimately, it was a missed assumption (he wrongly assumed "it was done using lithography, therefore it most certainly has to be original") on John's part resulting from his lack of knowledge of the S2 group litho recreations, and perhaps, moreover, his generally being under qualified to determine the validity of such a poster to begin with. Thanks.
