Rivista di astronomia e scienze affini, 1913, a. 7, n. 10 (October)
An 1913 Italian astronomy periodical issue from the Società astronomica italiana, produced with the Turin astrophysical observatory for a scholarly audience of astronomers. Its pictures are plain line plots of measured curves on gridded graph paper, alongside detailed engraved drawings of surveying and geodetic instruments such as theodolites on tripod stands, useful to a designer for technical diagram styling, grid layouts and precision mechanical line work.
