I have this card as well. A "preproduction sample" [in red letttering] variation of 1994 Finest 52 David Cone. The current set variations lists a set of cards that are protector samples. This is not a protector sample card. I just submitted an IR to add a sample / promo "set" which at this time, consists of 2 cards, as there is another thread that was submitted reporting an Ivan Rodriguez 126 with the same marking.
