Peter, you are incorrect in what I'm saying and also what I said in our email conversations.
no one, including you, has any real proof in what order any of the original posters were printed. No one has any evidence that Pacific Show Print posters were first, second, or 100th. The proof doesn't exist. When I said pressbooks and ads, it means pressbooks or ad sheets, not newspaper printed ads. No advertising materials exist or are known by anyone I have ever spoken to. Therefore it is impossible to flatly state that PSP or other posters are before other posters. The variety of images even for what people believe are original release items is no help, and like a number of other people I know, we do not agree with your declaration that the PSP poster or any other is the #1 from which sprang the rest. Your research is cool, but there just isn't enough to make the statement that the PSP poster is first. We don't know, and will probably never know as there is a pretty good likelihood that the advertising materials (pressbooks or ad sheets) no not exist and may have never existed for an exploitation film of this nature.
The loing hair version I said in our emails was sometime between 1939-early or mid 40s and no later. You said it was 1950s and I disagreed.
when teh day comes you find the exact images - not near images - published anywhere, I'll listen to that. Until then, all there is in conjecture and conjecture doesn't win prizes.
