This is an original antique advertising pinback button for the J.I. Case Threshing Machine Company of Racine, Wisconsin featuring the company’s iconic Case Eagle on globe logo, c. 1904. A great pin for the collector, and a patriotic one!
1.25” in diameter. Some aging to the celluloid, some spotting around the edges and surface rusting to the metal back, but overall in good shape for its age.
