Practical draughtsmen's work
A practical manual of mechanical drawing by Paul N. Hasluck, published in London and New York by Cassell and Co. in 1901, aimed at working draughtsmen. The pictures are fine line diagrams in black on cream paper: dashed construction lines over solid outlines, cycloid and curve layouts, and stepped sectional elevations with lettered parts. A designer could take from them the look of precise technical linework, with dashed guide lines and labelled sections.
