Bollettino dell'Osservatorio della Regia Università di Torino, 1886 (vol. 21)
This is a 1886 volume of meteorological bulletins from the Royal University of Turin's observatory, compiled by the Osservatorio astronomico di Torino for scientific readers. The pictures are monthly chart sheets of barometric pressure, temperature, vapour tension and relative humidity, drawn as wavy ink traces on squared grids with Italian labels and day numbers along the base. A designer might take the dense repeating line rhythms and the tabular grid structure as a model for data-driven graphics.
