Rivista di astronomia e scienze affini, 1909, a. 3, n. 05 (May)
An 1909 Italian astronomy periodical issued by the Società astronomica italiana with the Turin observatory, aimed at amateur and professional astronomers. Its pictures are technical: a geometric diagram of circles and construction lines, a mounted refracting telescope on a cast iron stand, a shaded star-chart grid with compass labels, and a sectioned lens tube. A designer could draw on the precise line work of the diagrams and the clean mechanical drawing style of the instrument.
