Annals of the Astrophysical Observatory of the Smithsonian Institution
Annals of the Astrophysical Observatory of the Smithsonian Institution, published in Washington by the Government Printing Office in 1900, is a scientific annual recording solar radiation measurements and spectroscopic work for astronomers and physicists. Its pictures are plain line graphs of wavy traces, sine-like curves, stacked spectral strips and a monthly bar-style plot, offering a designer abstract rhythmic linework and grid-based chart layouts.
