It is shaky screen time for San Francisco.
These fascinating front and rear images show how the city has changed in recent decades.
Some parts have been transformed – such as Haight Street, where the Haight Theater stood in 1948. This has now been demolished and modern buildings are in place.
In other areas, the heritage of San Francisco is remarkably intact – China Town in 1910 looks surprisingly like today's version.
Other comparisons presented here are the Flood Building, Lombard Street and California Street.
Scroll down for a fascinating look into the city's past …
