I noticed that L.A. Observed had an item on the reissue of “Los Angeles: A Guide to the City and Its Environs,” a book that is well worth having. The Daily Mirror HQ acquired its copy (formerly the property of Fremont High School--ahem) back in the 1970s and it has provided many hours of entertainment (check out the Chapman South American Chinchilla Farm, 4957 W. 104th St., admission by telephone appointment only).
The book has been reissued previously and is available on Bookfinder, although the price may be a little steep.
As a public service, to accompany your new/used copy of the WPA guide to Los Angeles, here are scans so you can make your own bookmarks from the Pickwick (d. 1995), 6743 Hollywood Blvd.
