Some impressions of the Paris Aero Show
A 1927 technical report from the NASA Technical Reports Server, collecting impressions of the Paris Aero Show for aeronautical engineers and aviation readers. The two pictures are pen line drawings of aircraft structural parts: a formed metal fitting with bolt holes and a wide flanged plate with a central circular panel. A designer could draw on their clean outline style, with simple contour lines and hatched shading that suggest curved sheet metal.
