Rivista di astronomia e scienze affini, 1911, a. 5, n. 12 (December)
This Italian astronomy periodical, issued in December 1911 by the Società astronomica italiana with the Turin Astrophysical Observatory, served a community of professional and amateur astronomers. Its pictures are grey halftone plates: soft smudged shapes resembling comet or nebula drawings, a large observatory telescope under a dome, and a diagram of plotted curved paths on a ruled sheet, offering a designer tonal blur, dome architecture, and technical chart linework.
