Comparison of United States and British Standard Pitot Tubes
A 1920 technical report from the NASA Technical Reports Server comparing United States and British standard pitot tubes, a measuring instrument for airspeed and fluid flow. The first picture is a dimensioned engineering drawing of a U.S. Navy pitot-static tube with a row of small holes along its length, and the second is a photograph of a long slender tube mounted on a bracket against a plain grey background. A designer could take from them the clean line-drawing style of technical dimensioning and the stark, minimal look of a plain object photographed in isolation.
