Electrical Experimenter 1917-10
A monthly American popular-science and radio magazine edited by Hugo Gernsback, this October 1917 issue addressed amateur experimenters, wireless operators and hobbyists during the First World War. The indexed cover is a flat-color lithograph of uniformed signal troops working spark transmitters and listening gear in a pink trench, with arcing signal trajectories against a yellow sky and shellbursts on a green horizon.
