Just wondering if that paper lose was an issue the paper stock had pre-production. Have you ever seen a blank back without the Diamond D stamp? Btw, when I did some research many years ago I found Diamond was a large match mnfg at the time these cards would have been produced. I don't believe I ever found the exact stamp on other material but if I recall I found other artifacts with very similar stamps. Unfortunately I lost all of my research when one of my computer hard drives crashed...
