Measuring 3-1/8x5.25" w/a total of 60 cards issued, the 1964 Topps Giants set was the company's first oversized issue. Color photo fronts w/card backs that include another player photo along w/a career highlight feature. Each card was not printed in equal quantities w/seven players being short-printed, including legendary icons Willie Mays and Koufax. Although his career peak was quite short, Sandy is widely regarded as a Top 5 left hander of all-time and was elected into the National Baseball Hall of Fame in 1972. The offered Koufax card has a bold and well placed signature and is highly sought after due to its short-print status, certainly a tough combination to beat.
