Offered here is an original 1937industrial blueprint produced by Dover Boiler Works of Dover, New Jersey,depicting the design and construction specifications for an 18" x 24"steel manhole assembly.
Executed in the classicblue-and-white blueprint process, the drawing contains detailed engineeringviews, cross-sections, measurements, fittings, hinges, eye bolts, washers, andfabrication instructions associated with a welded steel manhole cover. The precisionand clarity of the drafting make it both an attractive display piece and afascinating industrial artifact.
Particularly interesting is thedirect connection to the brewing industry. The title block identifies thecustomer as "Dr. Carl Reich & Son," while a contemporaryhandwritten notation on the reverse reads:
"Steel Manhole for PhoenixBrew Buffalo N.Y."
This notation almost certainlylinks the drawing to the historic Phoenix Brewery of Buffalo, New York, one ofthe many industrial brewing operations that helped make Buffalo a majormanufacturing center during the late nineteenth and early twentieth centuries.
The blueprint was created by DoverBoiler Works, engineers and contractors based in Dover, New Jersey. The drawingis dated March 8, 1937, and bears an approval notation dated March 9, 1937,indicating that it was a working engineering document rather than a laterreproduction.
The large format and strikingvisual appearance make it equally appealing to collectors of brewery history,industrial Americana, engineering ephemera, and architectural or technicaldrawings.

HISTORICAL INTEREST:
Industrial blueprints such as thiswere produced as working documents used by fabricators, engineers, andcontractors during the construction and maintenance of industrial facilities.The drawing illustrates the exact specifications required for a steel manholeassembly, including hinges, fastening systems, dimensions, and installationdetails.
The connection to Phoenix Breweryadds another layer of historical interest. During the first half of thetwentieth century, breweries relied heavily on custom-fabricated tanks,vessels, and access systems. Drawings such as this one document the infrastructurebehind brewing operations and survive far less frequently than advertisingmaterials, labels, or bottles.
Today, original brewery-relatedengineering drawings are increasingly appreciated both as historical recordsand as visually striking examples of industrial design.
