However, no one is going to call the 1989 OPC baseball set a parallel of Topps. That's what this looks like - What is the difference between Paramount and Desilu?
This looks like 2 different issues to me.
Edit: and now, after reading the article, I really think they are 2 separate issues. Maybe have the 1968 copyright be a related set (since it looks to be a test issue or something of that variety). Obviously, the guy opened a full box of the cards and didn't get any of the other copyright date ones, so it's not a parallel that was issued in the same packs.
