Elly,
No, the posters are not mine, although I own one or two (probably not originals, and definitely not any of the much older ones).
I have a CD with images of posters, that I received from another JWMB member, Les Adams. I met him at the Dean Smith Celebrity Rodeo in Abilene, Texas a couple of years ago. He is a foremost authority on John Wayne and his films, and you will see some of his work extensively throughout IMDb, where he has made numerous corrections to erroneous information.
Anyway, Les probably owns many of the posters pictured (if not all), and it is with his permission that I have been sharing these images on the message board, to add yet another dimension to an already rich tapestry of information about John Wayne and his movies.
