Up for sale is an authentic, vintage cast iron industrial brand plaque featuring the iconic "CHICAGO PNEUMATIC" nameplate. Unlike lightweight reproduction tin signs, this is an original, heavy-duty cast iron piece salvaged from early-to-mid 20th-century large-scale machinery (such as stationary compressors or industrial foundry equipment).

The plaque features highly raised, embossed block lettering painted in classic industrial navy blue over a bold red background. It includes original integrated mounting points on each outer edge. This substantial piece of industrial Americana displays an exceptional, honest patina with minor paint wear and weathering that underscores its authentic mechanical history. A perfect statement piece for collectors of "rustalgia," garage decor, tool enthusiasts, or industrial history buffs.
