Brian, Crown Central Petroleum and Standard Oil are inded separate companies. Crown started in the east Texas oil fields in 1917 and by 1920 had a refinery. In 1930 they moved the corporate offices to Baltimore and began retail gasoline marketing in 1933 in the eastern states. They are still marketing today. The winged Crown emblem probably is the one dating from 1945-1966. On the Phillips 66 neon sign...it is a beaut! I saw it when Mike had it for sale and if I hadn't already had flattened my wallet, it would have been mine. LOL A great sign!
