Joe DiMaggio has signed this 1941 Double Play card in blue Sharpie and it's about as bold a signature as we've ever seen from the Yankee Clipper. PSA/DNA has given an autograph grade of 9, so they clearly agree. The autograph looks like the lightest bit of pressure was taken off the "J" in the upper loop, while the lower loop's outer edge may have barely trailed off the cardboard at left but make no mistake, this is a beauty!  He's pictured alongside King Kong Keller, Joe D's outfield accomplice over 11 glory-filled seasons, and the card, while Authentic in grade, looks pretty clean overall.
