Not sure if this helps but I have a unique card that was graded by PSA just recently.
1909-11 T206 CY SEYMOUR THROWING, SWEET CAPORAL 350, FACTORY 25 PSA 2
It is the only one graded by PSA with that front back combo on their pop report.
He is on the list of possibles but just wanted you to know I have it.
Peace, Mike
