Found this interesting digital map of San Francisco in the David Rumsey Map Collection. It was a massive wooden model of San Francisco that has not been on display in one piece since 1942. The 158 pieces that create a 42×38 foot model of the city were digitally photographed and pieced together to create one big mosaic image. The model represented the city as it was in 1940.
