(The additional signatures of McCarthy, Selkirk, Pearson, and Hadley have been deemed clubhouse examples by PSA.) Signatures range from 1/10 to 6/10, averaging 3/10. The ball is lightly toned, with a few tiny age spots, but all the manufacturer's labels remain bold. Excellent condition overall. Accompanied by a vintage J. deBeer & Sons retail box which is not original to the ball. Full LOA from PSA.
