3-1/8x5.5" paper folder for Post Corn Toasties premium glow-in-the-dark ring from 1946 (see next item). Great illustration on front of Buck wearing, proudly, this same ring plus a larger inset illustration of the ring itself. Contains detailed information about the ring, its uses and "Atomic Secrets." Additional illustration on inside depicts ring on a hand with the planet Saturn illustrated in the bkg. both above the bold text "This Tells About The Magic Quality Of BUCK ROGERS RING OF SATURN." Folder has 2 vertical folds as printed plus 3 horizontal creases most likely from being wrapped around the perforated cardboard which held the ring for mailing. Cover has just a trace of missing orange color above the word "Magic" but all else remains clean and as issued. Our last example in essentially the same condition exceeded $1,000.
