Vintage Mastercard Counter Display Master Charge Interbank

Fun vintage Mastercard store counter application holder display. It's tan colored hard plastic with "Master Charge The Interbank Card" printed on the back. This is so old that the service mark application was still pending! Nice condition overall but does show some discoloration and minor expected scratch and scuff type wear. There are two marks on bottom where it looks like it was taped to the counter, as shown. 5" high,3 3/4" wide and 3 1/4" deep.
