Pitcher Luke "Hot Potato" Hamlin earned his nickname by having a propensity to juggle the ball while preparing to pitch, handling it like a hot potato.  Though he spent five seasons with the Dodgers, he fell out of favor with manager Leo Durocher and wound up spending his final three seasons with three different teams.  Authenticated by PSA/DNA, this 1940 Play Ball was signed lightly in black ink near the bottom of the card.  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.  Hamlin died in 1978, making signed examples of his signature difficult.
