This is a Mike Dunne Official National League autographed baseball signed on the Sweet Spot. What makes this ball unique and different from most others, is that he wrote his full name on the ball, Michael Dennis Dunne. This ball was obtained from a reputable major auction house. It is not individually certified but I have shown the JSA letter of authenticity from when they were obtained. Nice legible, smudge-free signature. Please review the photos as the ball pictured is the ball you will receive. Thank you for taking your time to view our item. International shipping is 15.00.
