This photo postcard captures three-time Cy Young award winner Sandy Koufax of the Brooklyn/Los Angeles Dodgers donning his original Brooklyn baseball cap in what appears to be from a Spring Training photo session. The sepia tone-style pic has been signed beautifully across the middle by Koufax in blue fine-tip marker. Koufax signatures have always been considered some of the hobby’s nicest and most legible. The autograph has been authenticated by JSA.
