Report of the Commissioner of Patents for the year ..
This annual report from the United States Patent Office, printed in Washington in 1849 for the House of Representatives, covers patents and agricultural inventions. Its single picture is a woodcut of a fruit tree trained against a vertical stake, with a bare branch cut away at the upper right. A designer could take from it a simple, legible botanical line style with fine hatching for foliage and a grounded, centred composition.
