Traffic Signals from the 1930s-1950s are disappearing with progress.
The TV series Streets of San Francisco
and The Lineup are excellent archives
of these details and other street acoutrement such as police
call boxes, phone booths, and train switches.
San Francisco is itself a work of art. Mister
SF's photo series marks the death of a small detail, perhaps. But, as
with all great art, every brush stroke matters.
