It's actually a 'PG' manufacturer mark and yes that would make it a different issue. I haven't seen that one before and it's not in the new guide Pat was working on or any of the additions I've added since taking over. Trouble is I'm not so sure where it fits in chronological order since the Carter Club series of cards followed the Firekeeper's Club Red/Silver/Platinum cards.

If you have any extra to trade of the PG version, let me know!
