Authentic double-sided metal retail advertising sign for Master Charge featuring the iconic overlapping red and yellow circles design with "THE INTERBANK CARD" tagline. This store display sign would have been prominently featured in shop windows or at cash registers to inform customers that the establishment accepted the Master Charge credit card before it was rebranded as MasterCard in 1979.

The sign displays the distinctive Interbank "i" logo in a black circle in the lower right corner, signifying the card's connection to the Interbank Card Association founded in 1966. The bold graphic design with its clean typography and distinctive overlapping circles exemplifies mid-century commercial design and banking history.
