Rivista di astronomia e scienze affini, 1910, a. 4, n. 07 (July)
This is an 1910 Italian astronomy journal issue, the Rivista di astronomia e scienze affini, produced by the Società astronomica italiana and the Turin observatory for working astronomers and instrument makers. Its pictures are plain black-and-white line engravings and photographs of instruments: a telescope on a tall pillar stand, a polar scatter diagram with an elliptical fit, a portable chronometer in a wooden case, and a labelled apparatus drawing, offering a designer clean technical diagrams with strong silhouettes and scientific labelling conventions.
