Vintage Brass Great American Belt Buckle Chicago Lion 1980

Vintage Brass Great American Belt Buckle Chicago Lion 1980. A Beautiful Vintage Belt Buckle from Chicago and Specifically I believe given to Lincoln Park Zoo Employees. Serial numbers etc are pictured. I cannot find a duplicate anywhere. Only a pure brass with no color that sold for 70 dollars!!! I'd say this is a Rare piece of Chicago History. Purging what no longer and never did suit. Xo thanks for looking !
