“The old and new in maps. Quite a contrast between the modern map in the background and the powder horn map being held by Miss Betty Jones at the Library of Congress. The horn maps, made from the horns of bullocks, were so much used in early Colonial Wars, 1739 to 1760, and during the Revolutionary War, that they were a necessary part in military equipment. They are considered the earliest American road maps, since they related principally to inland parts of the country, the skillful engraving showing New York, Quebec, and other early cities, and the trails leading to them. They also carried the British coat of arms and the name of the owner: In Colonial days the powder horn maps were given as prizes instead of silver loving cups as of today, and they were handed down from one generation to another as heirlooms.” – November 17, 1930 via Library of Congress, no known restrictions https://www.loc.gov/pictures/item/2016878953/
