Rivista di astronomia e scienze affini, 1912, a. 6, n. 01 (January)
This 1912 Italian astronomy periodical, the January issue of the Rivista di astronomia e scienze affini, was produced by the Società astronomica italiana with the Turin observatory and addressed a scholarly readership of astronomers. Its pictures are plain black-and-white line engravings of instruments and diagrams: a surveying theodolite, a cutaway diagram of a lettered oval, a variable-star light curve on a grid, and a refracting telescope on a tripod stand, offering a designer clean technical line art with precise labelled detail.
