Rivista di astronomia e scienze affini, 1912, a. 6, n. 10 (October)
This 1912 Italian astronomy journal issue, the Rivista di astronomia e scienze affini, was produced by the Società astronomica italiana with the Turin observatory for specialist readers of astronomy. Its pictures are plain geometric line diagrams in black on cream paper: a point and axes with a small angle, a circle with chords and lettered points, a semicircle with perpendiculars, and a circle with angle arcs. A designer could take their clean technical linework and labelled schematic style for scientific diagrams.
