This is another new entry from Leaf, which I'm on the lookout for to add to the Hoard. This card features 6 Dallas legends: Emmitt Smith, Troy Aikman, Bob Lilly, Michael Irvin, Bob Hayes and Herschel Walker.
This is the Purple version, shown here and serial numbered to 20. The serial # is hard to see on this image, but it is in the lower middle, between the names of Hayes and Walker.
There are at least 6 versions of this card in addition to purple. Gold, silver, magenta, platinum blue, red and a base relics card.
