WWII HONORABLE DISCHARGE RUPTURED DUCK SIGN PLAQUE ADVERTISEMENT
The Honorable Discharge Emblem, designed to be worn on the military uniform, served as proof the wearer was an honorably discharged veteran returning from service during World War II. It was unofficially utilized as an identifier to railroad, bus, and other transportation companies who offered free or subsidized transportation to returning veterans.
Even though it depicts an eagle,
the design of the eagle seems to depict its breast bursting through the button as though it has ruptured, and the eagle was believed by some to have been so poorly designed as to resemble a duck rather than an eagle. The term "ruptured duck" was coined to refer to it on that basis.
Not sure what these round signs would have been used for, I have tried to look up information about them, but unable to find any. They measure 5 3/4 inches in diameter. There is a hole on top and bottom. They were well taken care of, they are not weathered at all only minor signs of wear.
See pics.
