Illinois Malleable Iron Company catalogue
A 1916 trade catalogue issued by the Illinois Malleable Iron Co. of Chicago, aimed at plumbers, heating contractors and builders, listing malleable iron pipe fittings, valves, faucets and boiler and radiator trim. The four pictures show engraved and halftone views of a three-way valve body with hex union ends, a bibb-style valve with a long lever handle, a flanged valve with a bonnet, and a threaded union coupling, drawn in dense stipple and cross-hatching that a designer could borrow for industrial or mechanical line art.
