​​​​Original oil and gas vintage magazine ad for UNIT CRANE SHOVEL CORPORATION.  Trenchoes in the field, on the highway.  Where pipeline goes, the unit goes.  Traction and power for continuous ditching to meet pipe line schedules. Main office was located at 6411 West Burnham Street, Milwaukee, WI.  
This 1959 one page old petroleum drilling industry trade advertisement would display beautifully matted and framed.
