Blueprint reading; a practical manual of instruction in blueprint reading through the analysis of typical plates with reference to mechanical drawing conventions and methods, the laws of projection, etc
A 1919 technical instruction manual from the American Technical Society in Chicago, written by Howard Parker Fairfield, Ervin Kenison and Edward B. Waite to teach shop workers and drafting students to read machine drawings. Plates alternate between white-on-blue blueprint facsimiles of valves and fittings, dense with dimension lines and threading notes, and line-engraved sectional elevations of oil engines useful as ready-made technical ornament.
