I love this set, and have considered chasing it a number of times.
They used to show reruns of the show on the Disney channel back in the 80's....that's when I discovered it as a kid, and was probably the first time I ever saw live action video/film of some of the greats of the game (Mays, Mantle, Aaron) etc.
But alas, every time I've considered chasing it, I have wisely decided not to start because it would not be a cheap endeavor.
As far as advertising, I did come across this old REA listing. I don't think this is the advertising you were thinking of, but this is a cool piece:
