Among the best Williams signed balls we've seen is this gorgeous blonde Hall of Fame beauty inked by The Thumper on the sweet spot. The circa 1966 signature, in blue pen, stretches nearly from the Spalding stamp at left to the Cooperstown stamp at right and boasts a stylish and dramatic sweep to the "T". The magnificent penmanship rates a near flawless 9/10 and the ball itself as NRMT with just the slightest tan coating and not a scuff or nick in sight. A true "Splendid Splinter" of a ball.
