Outstanding card from the 1996 Leaf Signature series, carefully signed in beautiful penmanship by the only player to gain unanimous selection to the Hall of Fame.  Rivera's signature has been applied in black Sharpie.  The 1996 Leaf Signature issue included one signed card per pack, with more than 250 different players signing cards for this issue.  This example has been graded MINT 9 by Beckett, the corners sub grade of 8.5 slightly reducing the technical grade of the card.  The autograph itself has graded a perfect GEM MINT 10.
