Original industrial identification plate that would have been mounted to a piece of Challenge printing or print-finishing machinery. Raised lettering reads:
“MANF\'D BY THE CHALLENGE MACHINERY CO.
GRAND HAVEN, MICH.
AND CHICAGO, ILL. U.S.A.”
Features two original mounting holes, one at each end.
Nice naturally aged surface with dark patina and areas of green verdigris/oxidation. Back remains unpolished and shows substantial age-related oxidation. I have left the piece exactly as found rather than cleaning or polishing it.
Great piece of antique American industrial history for a letterpress collector, printing enthusiast, Challenge Machinery collector, steampunk display or vintage industrial decor.
Please see photos for exact condition.
