Pittsburgh Pirates PNC Park Exclusive SGA Canvas Autographed by Buccos Legend Bill Mazeroski. Beautiful Black and White Image of Maz’s iconic trip around the bases after his Walk Off HR during Game 7 of the 1960 World Series. Canvas measures approximately 9x12 inches. Perfect, Bold Signature in Blue Sharpie Marker with 10-13-60 Inscription. Signature was personally obtained during a recent Private Signing I held with Maz. No COA. However, I can provide something much better, a photo of Maz signing this EXACT item will be included.
