Original oil and gas trade magazine vintage ad for CONTINENTAL OIL COMPANY. Conoco President L.F. McCollum, hats off to supply men. Tremendous amounts of varied efforts and skills are required to search for oil and gas, drill wells, produce oil and gas, transport the energy in the raw, process it, and distribute it in usable form to consumers. In the complex structure of the oil business, each function is vitally important. This unique 1959 old petroleum industry magazine advertisement would display beautifully matted and framed.
