"Oil Wells, Olinda, California," issued by SUB-POST Card Co., Los Angeles, ca. 1910s. The photograph shows a horse-drawn vehicle in the foreground with some structures, a tank reading "Union Oil Co. of Cal." and a graded hill with several oil derricks on it. At the base of the hill at the right is a small portion of what appears to be Carbon Canyon Road. The card does not have any printed matter on the reverse and may not have been a postcard. The condition is good.
