Vintage ballpoint signature, "Sandy Koufax,” on the reverse of an off-white 5.5 x 3.25 government postcard postmarked July 19, 1965. In very fine condition. Encapsulated in a PSA/DNA authentication holder.
In a career loaded with stellar seasons, 1965 proved to be the pinnacle of greatness for Sandy Koufax, who, despite constant pain in his pitching elbow, set a then-major league record with 382 strikeouts (a feat that remains the top mark for NL pitchers and left-handers), pitched a major league-leading 335 2⁄3 innings, threw a perfect game, won his second pitchers' Triple Crown—leading the league in wins (26), ERA (2.04) and strikeouts—captured his second unanimous Cy Young Award, and won his fourth and final World Series title, earning the series MVP award in the process.
