Ethyl Gasoline Corporation was a joint venture between G.M. and Standard of New Jersey. The name of the company was changed to Ethyl Corporation in 1942. They're still in business today. I don't know how long G.M. was involved with the company. If you researched it I think you'd find that Ethyl Gasoline Corporation owned the Ethyl patents, not G.M. G.M. might have sold their portion of the Ethyl Gasoline Corp. I've got that info somewhere, finding its the problem. Anyway, Dick's sign is one of the earliest Ethyl signs. Its probably from 1923 or 24, before the GM/Esso partnership.
