Is there a parallel of this set involving the pack attack numbers?  For example,  I have Derrick Johnson #2 with a lighter back and a 3 of spades, and another Derrick Johnson #2 with a 10 of Spades and a darker back. It seems that the paper is different, but I am not sure.  I just wonder how many variations of these there may be. So far as I can tell, everything else is identical.
