Bollettino dell'Osservatorio della Regia Università di Torino, 1884 (vol. 19)
A bulletin of the Royal University of Turin's observatory for 1884, issued by the Turin astronomical observatory for a scientific audience of meteorologists and astronomers. Its pictures are monthly meteorological charts plotting barometric pressure, thermometer readings, vapour tension and relative humidity as day-by-day line graphs on squared grids with Italian labels. A designer might take the dense, rhythmic wave patterns and fine grid rules as raw material for abstract texture or data-visualisation backgrounds.
