Photo spread from Photo Memo No. 2, June 1946, featuring 3 photos (of 10 total) by Gordon Parks on pages 4 and 5. Text reads: "The vast establishment of the oil industry is first of all functional. Much of it is also beautiful. The intricate mechanisms which get crude from the earth, ship it where it is needed and transform it into hundreds of products on which our economy depends, often make fascinating patterns. A sampling of photographs showing the sweeping lines, the striking symmetry, and the intriguing designs of oil, appear on these pages."
