Lithography
Lithography by Joseph Pennell, published in New York by Frederick Keppel & Co. in 1912, is a treatise on the lithographic process aimed at artists and printmakers. The four pictures are grey monochrome lithographs of Panama Canal construction, with a steel gantry crane over a dry lock, massive concrete lock walls with tracks and timber, and a crane above a lock gate, showing hard perspective, dense crosshatching and industrial scale a designer could borrow for dramatic architectural compositions.
