What's better than an early-morning old-car id challenge? That's actually a '54 Super about to drown its Dynaflow. Note the upper-series cowl--that of the Special and Century differed from the Super and Roadmaster--and the three ventiports... only the Roadmaster had four in '54. (In '55, only the Special would have three.)
Among the other vehicles I see a couple of Chevrolets--perhaps three--and '52 and '53 Mercurys.... There is still an ARCO station on the corner.
Apparently it was a flood-prone intersection--the LAPL identifies the photo below as Sepulveda and Slauson, dated 1954. (That's a '52 or so Chrysler.)

And another, dated by the USCDL as January 13, 1952--the building at right is the same as the one above; at left is a Union Oil station:
