Did you pick it up from the original owner?
Any chance the original owner was in education?
I don't know about that exact item, but SI would do a hospitality room at some education conventions. Secondary school principals for sure. In the 70's/early 80's the handout to get autographed was a panel with photos of the three athletes they had there that night.
So maybe a similar thing from earlier or a different event when they only had him there?
That's about as close a guess as I've got.
As a long shot you could contact SI. They seem to have a decent dept for their own history and might know.
