Spalding official NBA basketball signed in black marker by twenty-one participants in the 1988 NBA All-Star Game, including Michael Jordan, Larry Bird, Magic Johnson, Hakeem Olajuwon, Patrick Ewing, Clyde Drexler, Isaiah Thomas, Karl Malone, Kevin McHale, Doc Rivers (twice), Fat Lever, Danny Ainge, Mike Fratello (coach), Xavier McDaniel, Alvin Robertson, Brian Hill, Brendan Suhr, and Maurice Cheeks. The Jordan signature is one of the boldest on the ball, grading 10/10. The remaining signatures range from 3/10 to 10/0, averaging 6/10. The ball, which has hardened with age, appears to have been overinflated at one time, which has caused some of the black trim to split and crack. In Very Good to Excellent condition overall.
