Both photos were taken c. 1919 and are from the Library of Congress site which indicates no known restrictions to their use. Several things struck me about these images: one was the location of oil rigs right next to the homes, and the second was the large number of rigs. Couldn't get away with that today, could we? You can also see flares where the distillate is burned off. Must have been fun keeping house. Must have smelled lovely, too, or maybe they just thought of it as the fine "smell of money being made."
