Rivista di astronomia e scienze affini, 1909, a. 3, n. 06 (June)
An Italian astronomy journal issue from 1909, the June number of the Rivista di astronomia e scienze affini, issued by the Società astronomica italiana and the Turin astronomical observatory for amateur and professional astronomers. Its pictures are catalogue-style engravings of instruments: a geared equatorial mount with a tube, a German-made telescope on a heavy cast stand, a Century refractor on a tripod beside a price list, and a boxed chronometer, all drawn in crisp black line with grey tone and no people, suggesting clean technical product illustration for scientific equipment layouts.
