Tom Sunkel managed to win nine games in 63 appearances with a 4.53 lifetime ERA despite being blind in one eye for four years of his career.  His signature was applied in blue ink, graded MINT 9 by PSA/DNA.  The card originates from the Shibe Park collection of autographed cards, an original owner collection carefully collected by a teenage boy who, in 1939 and 1940, obtained many autographs from players arriving at the train station near Shibe Park, and continued for many years to obtain signatures in person and through the mail.
