Sorry for the small pic of this one. It's all I was able to pull up. This is a 2012 U.D. Exquisite Legacy Bookmark Jersey Autographs card, featuring signatures of both Bo Jackson and Herschel.
The card is is numbered ELBM6, and is serial numbered to just 10. I hope someday it finds its way to the Herschel Hoard. As usual, the above image is courtesy of COMC.com.
