I’m happy to recommend Bunker Hill Los Angeles: Essence of Sunshine and Noir, by my Crime Buddy Nathan Marsak, published in 2020 by Angel City Press. The book is full of historic photos and vintage ephemera, and the text is a deep dive into L.A. history in Nathan’s freewheeling style. If you’re fortunate and have a local independent bookstore, try it first.
Nathan is also the author of “Los Angeles Neon” (2002) which is out of print, but available from a variety of dealers.
Bunker Hill is in stock at Skylight Books, Book Soup and Vroman’s in Pasadena. Also available online from Angel City Press.
