[Balloon bulletins]

1918 · 3 pictures

A 1918 military aeronautics publication from the Smithsonian Libraries, apparently a set of technical bulletins on balloons, with diagrams likely intended for officers and observers. The pictures are plain line drawings: a perspective grid with horizon line and scale, a rotated plan and section of a parallel grille, and numbered sequences of tethered balloons and vehicles with ropes. A designer might take their clean technical diagram style, dense labelling, and schematic linework as reference for instructional or engineering graphics.
