Denny's Indexed Map of the City and County of San Francisco. Showing Official Grades and Subdivisions compiled from latest public and private data
Edward Denny & Co.
San Francisco, 1919
205 x 161 cm (81 x 63.5 in)
Huge, detailed map of San Francisco, showing military reservations, block and house numbers, parks and tunnels, etc. This is the largest of what were apparently three sizes of the map.
The map was sectioned and mounted on linen, allowing the user (for example a city surveyor) to take it out into the field and fold it to the panel which corresponded to his or her current location. It would also be a beautiful decoration for a large wall.
OCLC/WorldCat does not list any copies of this 1919 version (copyrighted 1918), but does list one copy of the 1914 edition (the large wall map size), and one copy of the 1912 edition (what would appear to be the small wall map size). There was also a smaller pocket map, though no copies are listed in OCLC/WorldCat.
Some discoloration and a few chips here and there.
