Rivista di astronomia e scienze affini, 1909, a. 3, n. 09 (September)
Rivista di astronomia e scienze affini is a September 1909 Italian astronomy periodical issued by the Società astronomica italiana with the Turin Observatory, written for professional and amateur astronomers. Its plates show sunspot or solar-disc drawings, a dark lunar or planetary surface view, and two observatory telescopes, one a small refractor on a tripod mount and one a large instrument in a domed room. A designer could draw on the hand-drawn charting grids and the ink-and-halftone rendering of dark disc shapes against pale fields, and on the sturdy brass-and-iron instrument forms.
