Those are flippin awesome! I am a Cardinals team set collector, and as embarrassing as it is to say..... I didnt even realize that their wasn't any Cardinals in the 1972 Topps In Action subset.
However, I do think Topps made up for it more than we think. Six of the in action cards form a Joe Torre puzzle on the back. I have an uncut version of the puzzle back.
Here is a picture.
