Bollettino meteorologico ed astronomico del Regio Osservatorio dell'Università di Torino, 1867 (vol. 2)
A meteorological and astronomical bulletin issued in 1867 by the Royal Observatory of the University of Turin, Italy, for scientists and observers recording daily weather. The pictures are printed daily-observation charts on squared grids, with each chart's ruled axes labelled in Italian, and a designer might take their tidy scientific layout, fine red and black trace lines, and dense tabular grids as models for technical graphics.
