This 1938 folder came with the following Silver Star Triple Mystery ring. 3.25x6.6" folder opens to 6.5x9.5" and describes and pictures all the ring's features to be used only by upper rank Silver Star members. Special messages were broadcast for these members who used the "Code Key" printed beneath the ring's cover to set their 1938 Telematic Decoder to the secret code key number. Folder has 3.5" hairline crease top front and fold line on left spine has 3.25" split, but all remains extremely clean. Back of folder has text of "Silver Star Official Poem." About the second we've seen, even rarer than the ring itself.
