Rivista di astronomia e scienze affini, 1909, a. 3, n. 02 (February)
This is a 1909 Italian astronomy periodical, the February issue of the Rivista di astronomia e scienze affini, issued by the Società astronomica italiana with the Turin astronomical observatory and aimed at astronomers and amateur observers. The three pictures are scientific instrument images: a large observatory refracting telescope in a dome, a mounted equatorial telescope drawn in engraved detail, and a catalogue advertisement for Century astronomical telescopes on tripods with price lists in francs. A designer could draw on their precise mechanical line work, fine tonal shading and clean, technical layouts.
