Annals of the Astrophysical Observatory of the Smithsonian Institution
Annals of the Astrophysical Observatory of the Smithsonian Institution, a government-printed scientific series from Washington issued in 1900 for researchers in solar radiation and infrared spectra. Its pictures are plain graphs and charts: scatter plots with fitted lines, a point-connected sunspot chart, and a line graph of solar constant values with predicted and observed traces on a grid. A designer might take the clean technical grid layouts, dashed and solid line styles, and small numbered data markers as an austere model for infographic structure.
