Rivista di astronomia e scienze affini, 1911, a. 5, n. 10 (October)
A monthly issue of an Italian astronomy journal published in 1911 by the Società astronomica italiana with the Turin observatory, written for professional astronomers and well-read amateurs. The plates mix engraved comet drawings with ruled coordinate borders, halftone sequences of planetary discs, a gridded cylindrical map of surface markings, and a hand-plotted light curve with fitted line — useful for grid overlays, faint tonal washes, and scientific chart framing.
