Where Are All of the Nice 1971 Kellogg's Cards?

I've got lots of 1971 Kellogg's cards.  Since I've been trying to collect all of the variations, I've been buying lots when I can.  Almost always, the lots consist of cracked, damaged cards.  Here are some examples of what I find.

I was able to buy a 1971 Kellogg's Football card set at the National a few years ago.  All of those cards are in nice condition.  Maybe I will need to do that with the baseball set as well.  I don't need perfect cards, but I would like cards without cracks, without creases and without scratches.

I really like the Cubs in this set.  That is the team that I cheered for so I want to upgrade those first.
