There are over 75 maps, atlases and posters in the collection and we will bring many examples for viewing at this talk.  Included will be a full-color bird's eye-view map of Los Angeles in 1871, a "Motor Relief Map of Southern California" issued by the San Fernando Branch, Pacific Southwest Trust and Savings Bank in 1923, an early map of the valley shortly after the opening of the Owens Valley Aqueduct and the San Fernando Plat Book from 1952.
