Stretching the full length of the postcard horizon, the Wood Mills complex looms over the Merrimack Canal like an industrial colossus — its endless red-brick facade punctuated by hundreds of windows, a lattice-truss bridge arching over the brilliantly turquoise canal in the foreground. At the time of this card's printing, the Wood Worsted Mill in Lawrence, Massachusetts was the single largest worsted wool mill on earth: 1,300,000 square feet of floor space, $3,500,000 in construction cost, and 5,000 employees — statistics the publisher proudly printed directly on the card's face. Built by William M. Wood of the American Woolen Company in 1905–1906, the complex was a monument to the Gilded Age's belief in industrial might as civic pride. Published by Louis Pearl of Lawrence and printed by Curteich Chicago, this unused linen card retains vivid color and sharp detail.
