Incredible find, unfortunately I had some problems with the production of the segment
If you look at the 1:56 minute mark, here is a picture of the scrapbook page with the two newly discovered cards.
Then you look at the same page at the 2:10 mark and it has the only other discovered California league GQ card. Obviously a photoshop job.
Then to continue their photoshopping job they put the three cards together and again fail to account for the relative sizes at 2:51.
