Kellogg's 3-D Football Card TV Commercial?

I've been waiting for a while to bring this up, but I purchased a tape from 1970 which appears to be a 1970 TV commercial for Kellogg's 3-D football cards.  Dick Butkus is supposed to be the star of this commercial.  I don't remember ever seeing this commercial.

Stay tuned and I will let you know if the tape is still viewable.  I need to take it in for processing.  Here is what the box looks like.
