Fantastic 8" x 10" original game action photograph of future Hall of Famer, Sandy Koufax delivering a pitch in 1966. Shot from a heroic low angle at Wrigley Field, Koufax is pictured during his final season; one in which he would achieve a career-high win total, going 27-9 before famously retiring at the age of 30 that November. Borderless photo has an angular top and bottom cut and image has clearly been cropped from a wider shot, contributing to a touch of visible graininess to the image. Still, a tremendous depiction of Koufax in full windup with just light obvious wear to the extreme corners. Heavy to moderate toning does persist on verso, mostly towards the left edge, with Koufax identified at the top in ballpoint. A date stamp of November 18, 1966, the day Sandy Koufax announced his retirement, appears at the bottom. Authenticated and encapsulated as a Type 1 photo by PSA/DNA.
