Original oil and gas trade magazine vintage ad for GENERAL GEOPHYSICAL COMPANY. Main office was located in the Houston Club Building, Houston, TX. Where accuracy begins. Visit the research development laboratories. You will find a hum of intelligent activity. The problem of the day may be the improvement of radio equipment for offset shooting. Or the development of a new seismic amplifier using transistors. Whatever the problem, you will see progress in the making. This unique 1959 old petroleum oilfield drilling industry magazine advertisement would display beautifully matted and framed. Nice graphics.
