Bronze. 63.5mm. 133.7g. Plain edge. Unsigned (Peter L. Kreider & Co., Philadelphia). These medals were given out to all commercial exhibitors at the fair. While some medals have the date engraved on the obverse, this one does not. The surfaces are at least 50% red with the remaining areas showing elements of steel-blue and violet. Excellent original eye appeal. Rarely seen in any condition let alone this nice.
