CED VideoDisc and Player Discussion

Way back in the dark ages of 9 1/2 years ago, I had a video class in my high school's art department. On the floor/tables in the one room of the art department were/ (probably) are many boxes of National Geographic to be used for art projects (collages, etc.). One day when my class had nothing to work on I looked through them. I was told that I couldn't have the few issues I wanted, but that I could remove some pages if there were specific articles I wanted. Of these I have finally found the issues for the year 1988 (the year I was born), and the issue from September(?) 1970 about the "Computer revolution", but I still don't have a copy of the unknown issue from the early 80s which features the ad embedded here. It is a single page front and back presented here side by side. If anyone can tell me what issue of National Geographic this was in (or a good guess even) I'd really appreciate it so that I can keep an eye out for it at my local junk stores and flea markets.
Thanks for any help, and enjoy the ad:
