Check out this interesting mock-up for the Expanded Universe figures. It is a Stormtrooper on Char-Broil cardstock. I am not exactly sure what this cardstock was intended for, but it does indicate that Engineering Pilots are developed on whatever cardstock is available at the time. The back of the cardstock is perforated for the fold-out diorama as seen on the Expanded Universe figures. While this is still intact, I would suspect that if opened, it would reveal a cutout similar to what was used for the production figures, with the exception of the graphics. The last photo shows a similar design of the Tamagotchi cyber digital pet toy by Bandai.
