BibliOdyssey has published concept drawings of Californian movie theatres from the Golden Age. The architectural sketches date from the late 1930s to the early 1940s, and include the Academy Theatre (above) and the Disney Theatre.
Movie theatres dominate the selection, but there are also illustrations of department stores and office buildings of the period (notably the Max Factor Building). All of the designs, some of which were never built, were conceived by architect S. Charles Lee. To see the article in full, or to find out more about the architect's life, just click here.
