I did a lot of work to crosswalk the 1933-1934 Goudey cards against the 1,530 photos featured in the "Conlon Collection" sets. You can read the full post by following the link, but I'll also share some highlights here.

* Explanation of why the 1933 Gehrig card looks a little weird
* Data showing the decreased use of Conlon photos over time
* Explanation of why Ruth looks so much older on his 181 card than on his other three
There's nothing life-changing here, but for those of you that like to dig deeper into these sets you may find something novel.
