An update for you and I Henry . . .
I've been able to study two early Old Judge paper packs with tax stamps that date to August 1st, 1884 and March 1st, 1886. They both have a notice on the underside of the flap which reads "EMBOSSED RICE PAPER READ NOTICE INSIDE" which seemingly makes reference to the insert I previously posted. It would now appear that the "rice paper" insert was placed inside the paper packs, likely discontinued with the migration to slide and shell boxes when the "Red Band and Flap" would migrate from a band attached to the wrapper to merely printed on the slide. The "Red Band and Flap" is often advertised in early Goodwin adverts, it is neat how it held the bottom closed, sealed the seam on the side, and doubled as a flap on top.
