How to improve woolen and worsted mill operations
An industrial trade manual on woolen and worsted mill practice, issued by McGraw-Hill in New York for mill managers, overseers and machinery buyers in the early twentieth-century textile industry. The plates are coarse-screen halftone photographs of factory interiors inserted as paired panels: spinning frames, carding and combing machines, dye vats, roving cans and roof trusses, printed dark and grainy, offering high-contrast machine silhouettes, heavy blacks and gritty photographic texture for collage and overlay.
