Hensley's map of San Diego is one of the earliest obtainable maps of San Diego to show all of the modern city.
Hensley proposed to the Trustees of San Diego on June 10, 1872, that he prepare a correct abstract of teh lands of the City, which was approved on July 24, 1872. He billed the City $27.50 for his work. The map was prepared in part to advertise his services as a title searcher. The map is the first map to show a list of the approved subdivisions around the City by name and for this reason is one of the most interesting early maps of San Diego, being the only map of the era to list and map all approved subdivisions through 1872.
