You’re looking at Muni Cable Car #522 passing through the intersection of Washington and Franklin circa 1955.
Service on this part of the Washington & Jackson cable car line was discontinued in 1956, but you can still visit Haas-Lilienthal House (seen in the distance on the right) thanks to sfheritage!
