Here's a power-pitching pair of exciting signatures on a 1964 Topps National league Strikeout Leaders card that is graded as a PSA 5. Sandy Koufax has signed boldly in blue Sharpie toward the bottom of his photo, his distinctive scrawl on full display. Don Drysdale has signed his smaller image as well and despite the constrained space, worked beautifully around his image. It's hard to believe but Drysdale passed on over 30 years ago; happily Mr. Koufax is still with us.
