Harmon Killebrew took some time to get his career established but once he did, there was no stopping the Bonus Baby that made good.  He's signed this 1956 Topps card low, along the bottom as oriented, just below the ersatz signature used by Topps, in a nice, rolling hand using a blue Sharpie.  PSA/DNA 9 is the autograph grade and it's about as nice as a 9 can get without being upticked. The card has been handled a little bit, with some rounded corners and slight scuffing apparent.
