A real photo postcard, "Oil Fields at Long Beach, Calif. 33K," ca. 1920s. The image shows about twenty or so derricks and associated structures reflected in a pool of oil. The pool is divided by a berm, on which, at left, two men are standing. The caption is at the bottom center of the unused card. With some soiling on the upper right of the photo and the reverse and minor edge rubbing, the condition is good.
