Basketball signed by six former Boston Celtic players: Tom Heinsohn, Sam Jones, John Havlicek, K. C. Jones, Kenny Anderson, and Antoine Walker. All the signatures are scripted in silver paint pen and grade either 9/10 or 10/10 with the exception of Anderson (black marker, 7/10). Sam Jones has also added his uniform number ("24") below his name. The Spalding NBA-regulation "Indoor/Outdoor" basketball displays several small surface blemishes and is in Very Good to Excellent condition. Full LOA from JSA.
