The Stereoscopic photograph
A 1901 treatise on stereoscopic photography by D. J. Ellison, published in New York by Underwood & Underwood, a firm known for stereoview cards, and aimed at amateurs and makers of stereo views. The pictures are mostly small black-and-white halftones and line engravings: a hand-drawn map with red route lines, an advertisement for camera lenses and brass fittings, a diagram of the Brewster improved stereoscope, and a classroom photograph of boys at desks with reading machines. A designer could take the simple, documentary tone of early halftone photography and the crisp engraved diagram style for vintage-science or instructional layouts.
