From the Los Angeles Public Library:
“Cars travel in both directions on Sunset Boulevard, at Sweetzer Avenue, in what is now West Hollywood. Seen are homes in the Hollywood Hills, Foster and Kleiser billboards for Grant’s whiskey and Ford automobiles, and a glimpse of the Chateau Marmont (right). Photograph dated March 14, 1950.”
Here’s a view of the same area, around the same time, taken from the roof of the Sunset Tower Apartments.
