I N C O R R E C T
again, I have 150,000-200,000 rolled modern age posters. I have SS posters that are theatrical release posters for US distribution. It varies by company. Very few titles are used for wilding compared to the number of titles released and generally they are top titles. Moreover, wilding really only takes place is cities where people do lots of walking - like NYC, Chicago. There is no purpose to go wilding in Las Vegas for instance because pedestrians are few and where they are, wilding is illegal (the Strip). Also, SS posters are very much used for International markets.
Good for you, Mr. Pedantic. You have a bunch of SS posters that, not surprisingly, never reached theaters. And you misunderstood what I said. No one was talking about international. No one was talking about non-major art-house companies. Of course, it varies by company, but the major studios were heavily-to-universally committed to DS by the mid-90's. Miramax was the last holdout until the disney takeover (just after Pulp Fiction) At larger US theaters, you almost never saw single-sided posters after the very early 90's (not including Miramax). By the end of the decade the same could be said of even the smallest theater.
Like I said, since the mid-90's the vast majority of SS posters (US, major studio, one sheets) were used for promotional purposed outside of in-theater display.
I'll clarify my limited wilding comment...
"If
a particular version of a poster is
only available SS (Fight Club Soap advances, His Cell/Her Cell Gattaca advances, TDK's joker playing card version, before it was used for the re-release) then it's more than likely a wilding issue."
BTW, if you google image search (GIS) 'wilding gattaca poster', it pulls up a giant selection of Brie's images...
