I recently submitted some autographed cards on-site for the new PSA combo autograph/card grading. The grader (I guess) immediately recognized the Walter Payton and Ted Kluszewski autographs as authentic. The first thing they did was to pull out a marker and make a streak on the back of each card. I about cried until they explained that the marker is the DNA that becomes colorless when it dries.

It's a pretty good service for cheap authentication of autographs on autographed cards, BTW.
