Apollo Commemorative Matchbooks

I first saw these strange little matchbooks on Retro Thing. Digging around Google resulted in more pictures, but little information, apart from what the article above states. The set of twelve matchbooks comes in a case, numbered as a limited edition item. The back of the case card lists all the technology RCA provided for the Apollo program, as seen below.

The matchbooks display Apollo mission patches on one side, and mission portraits on the other; also a montage of presidential portraits, for those involved in the program.
