Join author Peter Field for a public presentation and release party for the book, The Tenderloin District of San Francisco Through Time - a brief history of a neighborhood known to early San Franciscans as St. Ann's Valley. The story of this once-placid piece of real estate provides us with a fascinating microcosm of urban history. Join us as we examine numerous photographs and images, following the Tenderloin's turbulent passage and on-going efforts towards economic rehabilitation.
