1997 Century Marks Auto

This is the first time I have seen one of these pop up:

This is the Century Marks Autograph from 1997 Donruss Signature.  The blue background distinguishes it from the Millenium Marks (green) and the basic card (red).  In addition, the card is serial-numbered.  However, the Century Marks cards are just the first 100 of the 1,000 for the Millenium Marks cards.  Kind of odd.
