I have hunted through old Detective mags and the early digest pulps to find these images and then try and locate the cover where the image was finally used. Sometimes I see a photo and it can take me days to track that cover down, sometimes it drives me mad because I recognize the photo but just cannot find the digest cover it was published with.
These below are the ones I have located so far and where I can I will list the publication where the photo was found and the digest book in question.
