Graded GEM MT 10 by PSA. Hall of Famer, in a "Rookie Card" appearance. Among more than 10,200 examples recorded in PSA's census reporting, less than one percent have achieved this phenomenal tier. The elite grade, in view of a sticker/card's particular physical sensitivities, is particularly impressive. A flawless, early career depiction of the hardcourt icon, in Gem Mint condition.
