Football legend preprints

hey guys some people have got some ttms from nfl super stars of the past but sadly they are preprints, and im not talking about peyton manning or eli but john elway who instead of signing your card he will send his own preprint card which is not an actuall autograph its like the autographs on 2007 topps base cards.

troy aikman is another guy who will not sign the included cards but will send his own preprint shown below

brett favre is the final player that signs a preprint 4x6 but does have an address that he will sign your cards and are legit (i dont have) picture of preprint below (picture from funcorner youtube channel).
