Fascinating thread. That 1960 logo variation is an eye opener. Learn something everyday, or at least try to! I would imagine those Korean cards haunt many the player collector.
My rarest card (thanks to Joe T, who hunted this one down for me) is a signed 1952 Bowman Mantle. There are only 19 signed, as compared to 3400 graded unsigned in the PSA pop report. It is the second rarest of all signed basic issue Topps/Bowman Mantle cards, behind the 1952 Topps, of which there are 14 examples in the pop data.
