4 Different Movie Posters from The Son of the Sheik

These are four different posters from the film, "The Son of the Sheik." I was contacted by a reader named Amanda that owns these four posters. She was looking for information, including the estimated value of these posters.


The first two posters read: "By Popular Demand!" at the top of each poster. I know The Son of the Sheik was re-released many times. The biggest re-release being in 1937. If anyone knows more about the time frame and value of these, please comment or email me. Update: I received some great information from Jim on a few of these posters. The first one (Art Cinema), is the most common of the four, it is from 1938. The second one could be from the 50's or 60's since it has the same cover from the Irving Shulman book; however, both posters at the top read: "By Popular Demand," which could mean they are from the same time frame. We are still unsure about the second poster.
These two posters have similar font. The second poster, I have found out is from 1950. I have a newspaper ad with the same artwork for that poster. The horizontal window card, looks to have similar font, but, just as the first two, I am not 100% certain. Any information would be greatly appreciated.
