Here's a psa article detailing the set:

An excerpt in the article says... "The veteran collector has, however, seen an unfolded, empty wax box. This box and the fact that he has seen wax stains on cards are "clues" that these originated from wax packs.
Here is a link to a closed auction from Legendary Auctions for a 71 Greatest Moments Display Box:

It is interesting how the display box doesn't show a picture of an actual pack with a wrapper on the outside of it.
Here is a link to a guy who has the box...maybe he can lead you in the right direction. His name is unopenedpackguy.
