"Stern-Atlas" by Beyer and Graff 1925
This is a German atlas of the northern sky produced in 1925 by the astronomers Max Beyer and Kasimir Graff. It was probably the favorite atlas among German amateurs until the Falkauer Atlas came out in 1963. This atlas contained 50,000 stars down to magnitude 9 on 27 large loose sheets that are 16.5 inches by 22.5 inches.
