I have a fairly extensive collection of the Star Wars Topps vintage Sugar-Free gum pinups. For those of you who are unfamiliar with this card set here is what I know about it.
Here is a Star Wars Sugar Free Gum unopened sealed box.
Here is the outer foil wrapper to the Star Wars Sugar Free Gum box.
Here is an empty box of Star Wars Sugar Free Gum.
Here is a full Star Wars Sugar Free Gum box opened to see the packs of gum.
Here is a factory unused box.
Here is the bottom of the factory unused box.
Here are the four different Star Wars Sugar Free Gum packs.
Here are the four different Star Wars Sugar Free Gum wrappers.

Here is a look at the other side of a complete uncut sheet of Star Wars Sugar Free wrappers.
Here is a group of blue line proofs for the Star Wars Sugar Free wrappers. These proofs are usually found on paper stock and were used for corrections in the printing process. These were obtained directly from the Topps Vault.
This piece was obtained directly from the Topps Vault. They describe it as a oversize color key progressive overlay proof set. It features four color separation acetate overlays taped onto a white backing board. Each 7" X 10 1/2" acetate layer (yellow, cyan, magenta and black) lay on top of the other to make up the final image of the production box and the four different packs in each box. This is just my opinion but this piece was probably used for some mockup to show how the final product may look.
Here are some single sided color proofs. They are printed on a slick card stock.
Here is a box proof.
Here are five different blank back, cardboard stock, box color separation proofs. Each measures 11" X 17". Included are the Black and White, Blue/Yellow/Red, Yellow/Red, Yellow/Blue and Yellow proofs. Color separations are created during the final proofing stages of the set.
Here is a look at an original shipping box.
