Jahrbuch der hamburgischen Wissenschaftlichen Anstalten
Annual report volumes of Hamburg's scientific institutions, issued from 1883 by Lucas Gräfe & Sillem for the city's museum and laboratory staff and the scholars who read their research. The plates here are line graphs drawn on ruled grids: solid, dashed and dotted curves keyed by hand-lettered German labels (Roth, Blau, Gelb, Grün), plus tall stacks of year-by-year panels from 1910 to 1914, usable as period chart furniture, grid textures and curve shapes.
