We consulted many colleagues and San Francisco map experts and none have seen this map before, nor do we find record of any institutional holdings. It delineates San Francisco’s 41st Assembly District and its election precincts and extends east-west from Hyde St. to Lake & 8th Ave., and south-north from California St. to the Bay. This includes Laurel Heights, Pacific Heights, the Marina District, and parts of Russian and Nob Hill. The title box is placed in the Presidio.
The map includes a feature we have yet to see on any other antique map of San Francisco: East Van Ness Ave., running from Union & Polk to Lombard & Van Ness. East Van Ness appears in city directories from 1885 through 1894. It was surely a remnant of the famous Laguna Survey, said to have been conducted by Jasper O’Farrell in 1847/8. The survey ran at an odd angle to the expanding axis of the city grid. Eventually it was all but discarded, but this is a fascinating cartographic trace of the survey.
The original northern shoreline of the Bay is shown, showing how much of the Marina is built on landfill. Several spurious street names are shown in this area, including Tonguin and Lewis. These were planned but never actually created; Tonguin street is instead Marina Boulevard and Lewis is Marina Green Drive.
