Rivista di astronomia e scienze affini, 1912, a. 6, n. 08 (August)
An Italian astronomy periodical issued in 1912 by the Società astronomica italiana with the Turin astronomical observatory, written for professional and amateur astronomers. The pictures are geometric diagrams on printed pages: an ellipse orbit with labelled points and compass letters, and circles with chords and labelled arcs for spherical astronomy, drawn in plain black line on cream paper, useful to a designer wanting technical schematic or celestial geometry motifs.
