Oil field in the Los Angeles area, July 1928. The image is taken from a hillside and shows dozens of derricks, along with tanks, sheds and associated structures and elements. There are also power poles and what appears, in the foreground, to be fencing. On the reverse is a pencil inscription: "oil fields in Cal -- / July 1928." With soiling and some stains, as well as edge rubbing, the overall condition is good.
