Unique Kellogg's Items on ebay

There is an auction ending soon.  Wow!  The auction is for small cards cut off the back of Kellogg's cereal boxes.  That's not a big deal except that there are 116 cards with lots of stars.  They are also all from 1970.

I'm probably not able to afford this one, but I haven't seen anything like this.

Has anyone seen many cards like this?  I got a few from 1978 and that's it.

Can anyone even come up with a checklist of which cards were available each year?  I've only gotten a few unopened boxes so far.  I guess I should check out the ones that I see online to get some idea.

Update - this item sold for $333.
