We have a genuine vintage porcelain sign for sale, circa 1940s, that is rare and highly collectable! Stanavo Aviation Engine Oil was distributed through the Humble Oil and Refining Company (part of Standard Oil, which later became Exxon). Stanavo remained popular for many years - even Amelia Earhart was a fan and served as a spokesperson for the brand during the 1930s.

We Sell Only 100% Real Porcelain Vintage Signs

Our Stanavo sign is guaranteed authentic. Porcelain signs are becoming harder and harder to find nowadays because many of them were destroyed during World War II. Stanavo Antique Porcelain Signs are particularly valuable because of the brand’s popularity with Amelia Earhart, the first female aviator to fly solo across the Atlantic Ocean. We always protect our signs and keep them in their found condition, thus maintaining their value and charm.

Stanavo Aviation Oil - An Antique Porcelain Sign with Rich History

The Stanavo Specification Company was a subsidiary of Standard Oil and sold through an affiliate, Humble Oil and Refining Company. Stanavo soon became known as the Humble’s international aviation gasoline and oil. In the years before World War II, Standard and Humble operated over 30 various aircraft, including Lockheed Electra Juniors and Lockheed Vegas.

One Lockheed Vega that was part of the Standard Oil Fleet, model NC105N, underwent quite an ordeal during its time. Originally painted red with white trim, it was later painted to look like an eagle, named “No. 6” and known as the “Stanavo Eagle.” After an accident in 1931, it was later repaired by Standard Oil in 1933. Based on photo evidence, it appears the plane was part of the National Air Races. According to the NASM record, in 1936 the plane was equipped with landing gears from Art Goebel’s Vega and oil tanks from Amelia Earhart’s Vega. The whereabouts of the plane today are unknown as it may have been damage beyond repair during a flight in 1937.
