"Free inside every special pack you'll find a Dungeons & Dragons hologram. Lurking inside each hologram is a monster. Who knows which one's inside the pack? Maybe it's an Orc, or a Wizard, or even a Skeleton!"
The Dungeon Master made a cameo on the back of Shreddies packs in the eighties to advertise six collectable monster holograms that were 76mm by 50mm. Not sure exactly when these were in circulation but the copyright is 1986 and the box's best before date is September 1987.
