You are purchasing a very unique Harmon Killebrew autographed baseball. This ball was obtained as part of Jim Kaat's estate. I purchased a large amount of items directly from Mr. Kaat. This is one of many baseballs that were signed and given to Jim by other players. Ball is a vintage 1980's Rawlings Official American League (Bobby Brown) baseball. Ball is signed on the panel in blue ballpoint. Harmon added To Jim, Remember The Good Ol Days! as a message to Kaat. Signature is crisp and bold. Ball is clean and white overall. Authenticity is 100% money back guaranteed to pass any third party authentication. SUPER addition to any Twins collection!! Buyer pays $6.00 shipping. Shipping combined on multiple lots whenever possible. MN residents add 6.875% sales tax. Thanks for your purchases! Please check out my Ebay store for more great items!
