Binder presentation with 75 color maps most showing between two and nine city blocks, inserted loose as issued back to back in plastic sleeves, which are bound in a "Bar-loc" binder with cloth covers. 34.5x30 cm (13½x11¾").
Superbly detailed fire insurance atlas of San Diego from Sanborn, conveniently reduced in size from earlier versions, with correlative index at front. There are notes on some of the map, and several documents are laid in, one marked confidential. There is a key map, and 74 detail maps numbered 1-75 - map 52 was not printed. We can find no listings for this atlas in OCLC, though there are microfilm copies at the University of California Berkeley, Santa Clara Library, and the Getty Research Institute, noted as being reproduced from original copies at the Library of Congress, though we could find no LC listing.
The documents are located at the pages with the maps they are associated with.
Many pages are with original notes by an insurance underwriter. The Sanborn products were designed to write not only on the maps, but on the transparent covers of the maps, from which the notations could be removed.
The atlas is produced by the legendary Sanborn Map Company which produced incredibly detailed maps in XIX and XX centuries, created to allow fire insurance companies to assess their total liability in urbanized areas of the United States.
