2.5" square by 1.5" deep mailer complete with just small edge pieces gone from the mailing label. Includes 4" square instruction sheet which folds to 2" as it was inserted in the box. Front left half of the sheet has noticeably tanned with a few small gray marks as the original owner documented on the reverse his receipt of his ring "Received On 2/10/47 A.M." He also wrote a statement of ownership on the reverse which includes tracing his "Dynasty" back to his father and grandfather declaring himself "And Now His Excellency The III." The ring itself is Mint as issued except that like all examples the interior radio-active material had a brief half-life and no longer produces flashing atoms when viewed in the dark. Still a gorgeous complete premium and one of the most popular premium offers in the history of children's premiums.
