1945-46 Caramelo Deportivo #52 Fred Martin. Graded a 1 by PSA. Fred Martin had a short and unremarkable Major League career. He did, however, secure his place in baseball history years later as a minor league pitching coach for the Cubs when he taught a young prospect named Bruce Sutter how to throw a split-fingered fastball, a pitch Sutter would ride all the way to Cooperstown.

As with EVERY PSA card in this auction, if you would like to crack this one out and send it to SGC, I will pay for the grading fees if it doesn't get a bump in grade. This is not because SGC is more lenient than PSA. They are not. But they are more accurate. All you have to do is send me a scan of the card once it's out of the holder, so I can see it hasn't been damaged (it can be difficult to crack cards out safely) and then let me know what grade SGC gave it. If it's not higher than the PSA grade, grading fees are on me! Offer is good for 60 days after close of auction.
