Primarily Petroliana Shop Talk Forums Shop Talk Petroliana Forums General Petroliana Discussion Atlantic Imperial Shield Card

I just bought an Atlantic Imperial sign with a plastic shield at the bottom right and to the left of the shield it says "Get Imperial Shield Card Here" with an arrow pointing to the plastic shield. I would like to get a card to put in there but I cannot find what this card looks like. Any help in finding what this card looks like would be appreciated OR if anyone has one for sale that would be great. Thanks, Ken
