As my oldest son reached HS and got a job in a local sporting goods store he came home with these 5 x 7 inch prints of NIKE posters that were being issued at the time. The Nike posters were reportedly too big to display in the typical sporting goods store so NIKE provided each store a counter top display so customers could see what all the available posters looked like. My son got the NIKE salesmen to give him a few for our collection. Below we see pictures of the box these mini posters came in and the description of the initial counter top display device.
6/25/2020: Recent communication with a senior Nike employee resulted in this response "Our records from yesteryear weren’t the best and to that end, we have little definitive information about the actual number of poster cards made, which posters were included and when they were released." SO, anyone awaiting Nike to swosh in and verify or correct all this information is probably in for a long wait.

It appears that 6 digit "Nike numbers" exist for all the posters that were offered for sale. We have determined these catalog numbers by their presence on the front or back of the Nike poster cards, from catalogs and sales order forms, from labeling on the posters and/or from the labeling on the outside of the unopened plastic bags containing the rolled up posters as shown below.
