Luke Hamlin was a pretty fair pitcher during his nine year career in the bigs, best known for some fine campaigns pitching for Brooklyn and would notch 20 wins for the Dodgers in 1939. His Play Ball card from that peak career year is offered here as a fine looking canvas for a Gem Mint 10 PSA/DNA reviewed signature in black that simply shines. Hamlin missed the autograph show circuit glory days, passing away in 1978.  Some paper loss/remnants from long-ago scrapbook removal appear on the back, certainly not a deterrent given the rarity of the signature on a 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.
