The common flag is white with red Esso inside a blue oval ring. Loughran draws the ring extending throughout the field. A 30 November 1951 company letter to Harnack confirms the livery for Esso Transportation, Esso Petroleum and most New Jersey affiliates, with measured drawings. The museum’s 1966–67 flag measures 1727.2 × 2667 mm; its wording says oval where Rosanoski specifies an oval ring. Many affiliates used this shared livery, including Creole, Panama Transport, the Argentine concern, La Columbia, Skouras, Humble, Lago and Petrolea. Most continued using the group flag.
