I talked with Mary Ann earlier today and neither of us have been able to find out anything about this particular Circus Circus card. I emailed the seller and got a scan of the back but it's just a blank card with a magnetic strip and NO printing. It is not listed in the slot card guide, either the 7th issue last published or the new 8th issue Pat was working on and I've taken over. If anyone has any info on what this card was used for it would be appreciated. I would really like to know if it needs to be added to the new guide.
