Considered the model umpire of the post-war era, Chylak was a skillful arbiter who earned the respect of players and managers alike during his 25-year major league career. Rare ballpoint signature, “Nestor Chylak, Jr. American League” on an off-white 5 x 3 card. Signature is housed in a plastic PSA/DNA authentication holder. In fine condition, with light block of toning over signature and a small staple hole through “League,” not affecting signature. Only the second Chylak signature we have come across. LOA Steve Grad/PSA/DNA and R&R COA.
