This is an example of the President's Conference Committee (PCC) streetcar that was designed in 1935. These street cars were meant to modernize the look of the streetcar. They are the most prolific of all streetcars and 4,500 were produced and ran in 33 American cities, according to Streetcar.org. 1053 is painted in the colors of the Brooklyn, New York streetcar system. Streetcar.org calls the PCC, "The Streetcar named Success." - San Francisco, CA
Here is a dirty little Muni secret, most of those art-deco looking PCC streetcars didn’t come from the city it’s painted for. The PCC was one of the early “standard model” of streetcars which cities could essentially order off-the-shelf (though most had some sort customization) allowing Muni pretty accurately recreate streetcars that otherwise rusted to dust decades ago.
When the Philadelphia Transportation Company introduced its next-generation PCC streetcars in 1938 the company rebranded with a new livery... that looks remarkably like the packaging of a certain well know cream cheese.
