Scientific American, Vol. 92, No. 22 (1905)
This is a 1905 issue of the Scientific American weekly magazine, published in New York for a general readership of inventors, engineers and hobbyists. Its pages mix small trade advertisements, such as motorcycle conversion kits and carriage makers, with photographs of laboratory instruments like seismograph recorders and transmitters. A designer can take from them the crisp grey halftone look of early mechanical photography, with clean machined metal, dials and hand-drawn-style ruled borders suited to vintage technical layouts.
