It's time to screen wobbly for San Francisco.
These fascinating images before and after show how the city has changed over the decades.
Some parts have been transformed – such as Haight Street, which in 1948 hosted the Haight Theater. This has been demolished and modern buildings are in place.
In other areas the heritage of San Francisco is noticeably intact, for example China Town in 1910 seems surprisingly similar to today's version.
Other comparisons presented here include Flood Building, Lombard Street and California Street.
