Baseball HOFer, known for his spitballs and for his 41 1/3 innings in an eight-day span in 1908 in a futile attempt to bring the White Sox a pennant. Ballpoint signature, 'Ed A. Walsh, White Sox,' on an off-white 4.5 x 2.5 card. In fine condition, with some light show though from cancellation mark on reverse and clipped corners. COA Steve Grad/PSA/DNA, COA Mike Gutierrez/Global and RRAuction COA.
