Original oil and gas trade magazine vintage ad for CORE LABORATORIES INC. Main office was located at 801 Core Street, Dallas, TX. IBM 650 computer data processing center can retain 20,000 digits of information, remember instructions, and follow them with logical ability as it adds, subtracts, multiplies, and divides. This unique 1959 old oilfield petroleum industry magazine advertisement would display beautifully matted and framed. Nice graphics.
