Spectacular single-signed baseball was signed by the on the field leader of Wilbert Robinson"s "Daffiness Boys" at the peak of his skills. John Heydler ONL baseball falls into the 1928-30 span, putting it smack dab in the middle of The Babe's magical .393 batting season. Perhaps best of all it is in its original ONL Spalding box (which is now sealed shut) worth several hundred dollars alone. Authenticated by PSA/DNA, ball is graded a 7, and the autograph a 6, overall 6.5. Looks FAR better for a ball of this age and beauty. A classic.
