Rivista di astronomia e scienze affini, 1913, a. 7, n. 06 (June)
This 1913 Italian astronomy periodical, issued by the Società astronomica italiana with the Turin observatory, was written for astronomers and scientific readers. Its pictures are precise engraved and halftone views of surveying and astronomical instruments, including a theodolite-like instrument on a tribrach base, a close plan of a mounting with its adjusting screws, and a sectional drawing of a level or telescope tube. A designer could draw on their clean technical line work, exact proportions, and labelled diagrams.
