Hall of-Famer Enos Slaughter was captured as a Yankee in the Wilson Franks set, a 1954 Regional issue still popular with collectors today.  Slaughter powered four teams to World Series titles (2 Cardinals squads, 2 Yankees) and Wilson's certainly captured his signature well, as this BVG Authenticated Autograph shows, nicely following along below the card's printed version. Although it's unfortunately fading a bit, signed Wilson's cards are not often encountered.
