Original old petroleum trade magazine vintage ad for INTERNATIONAL HARVESTER COMPANY of Chicago, IL.  Puts ruggedness to work on any service job and keeps it working full time.  When cementing, well logging, fracturing, acidizing, dewaxing, or any other down-hole function is required, there's a specialized International chassis with more than enough strength, power and stamina to take a brutal pounding for long hours.  And these trucks will keep on working when the pressure is on. Model C-1202 and R-190 are shown.   This 1962 two page gatefold oil and gas trucking industry advertisement would display beautifully matted and framed.
