Report of the Commissioner of Patents for the year ..
This is an 1849 annual report of the United States Patent Office, printed in Washington for the House of Representatives and held by the Smithsonian Libraries; its engravings, though not patent drawings in themselves, show deer and bison in plain line engraving with stippled shading. A designer could take from them the crisp hatching and stipple of early nineteenth-century natural history plates, useful for animal studies with a period feel.
