You'll be excused if you can't place Tom Sunkel, who was a starter for three teams over six broken-up big league seasons, with half occurring during World War 2. He was, amazingly, blind in one eye but persevered for fifteen professional seasons, a truly amazing display of pluck and perseverance. He pretty much disappeared after his playing days and this is his sole signed 1939 Play Ball per the PSA/DNA database. The card is VG, a PSA 3 but the signature is a very solid MINT 9, with a compact and neat autograph laid down in blue ink.  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.
