According to change log, a color variation was added just over a week ago

for card 39:

Now the issue with this type of variation is typically that the normal version (the a in this case) are just as they appear, the red parts are red and the black parts are black. On the b variation, what this typicall is either everything is printed in red or black on first pass, and then second pass is another color. In all of the instances of the cards that have either the red or black headers/etc they all are red printing with black on top.
I had made a master list in the past for this set but I had given up on trying to complete that set because it is basically impossible, and that I didn't want to have up to 4 copies of every card in an 800 card set. There are many cards that have the same variation as the one mentioned above and I have a feeling that this type of variation is not valid for TCDB, especially since there are hundreds of printing errors that exist in this set that are not tracked on the checklist, such as the broken stat line issues, name alignment printing errors, or the cards of the Jets players that have pink on the team banner instead of white, and many others.
I have made inquiries to get a list of how many cards have the red/black stat headers printing error and hope to post that information soon.
