These two views, taken from the same location but separated by roughly 26 years, depict the dramatic growth Los Angeles experienced in the early twentieth century.

Both photographs show the East Hollywood/Los Feliz area and were taken from Mount Olive, today the site of the Barnsdall Art Park and the Frank Lloyd Wright-designed Hollyhock House. The eastern end of the Hollywood Hills appears in the background.
