Rivista di astronomia e scienze affini, 1912, a. 6, n. 12 (December)
This 1912 Italian periodical issue of astronomy and related sciences, produced by the Società astronomica italiana and the Osservatorio astronomico di Torino, was aimed at astronomers and scientific readers. The pictures are line diagrams of geometric figures and scale constructions, plus engraved catalogue views of surveying instruments such as a theodolite on a tripod stand and a telescope in a fitted wooden case, which suggest clean technical line work and precise instrument detail for designers.
