Well, I have found some scans of the Japanese GLBs and in the 13th one there were these playing cards. They're only spades, but I'm pretty sure the other suits are available as well. I looked at the later scans of the bibles, but I can't find them!
If anyone could provide me with some scans, I would be very grateful.
I know this is a very silly request, but since everyone here has been so helpful with my previous questions, I thought I'd ask...
Thanks in advance!
