1964 Topps Giants #3, Sandy Koufax SP.
Sandy Koufax is considered one of the top 3 left-handed pitchers in MLB history and arguably the best.
His final five seasons (1962-1966) are arguably the most dominant stretch of pitching ever seen. During this period, he won three Cy Young Awards and an MVP, had a 1.95 ERA, and recorded four no-hitters, including a perfect game. The legend of his brief, electrifying run has stood the test of time.
