Magnolia Gasoline may be the ultimate contradiction in terms--surpassing Jumbo Shrimp. Magnolias are a southern evergreen tree with glossy leaves and creamy blossoms, as shown on the sign.

The contradiction has long been resolved. The Magnolia brand disappeared into Mobil (now ExxonMobil) more than half-a-century ago.

This sign is at the Stokely Event Center, several miles from Rt 66 in Tulsa: www.stokelyeventcenter.com.
