OLIVER CORPORATION 1955 Little Boomer OC-3 crawler pipe vintage ad

Original vintage oil and gas magazine ad, THE OLIVER CORPORATION of Chicago, IL.  Little Boomer Oliver OC-3 Crawler and Hydraulic Boom do Real Big Job. Pictured is the Little Boomer laying pipe for a new housing development.   Old 1955 petroleum industry advertisement. 

On the reverse side (see Additional Images tab) is ROCKWOOD SPRINKLER COMPANY, of Worcester, MA. These Seats Keep Rockwood Unions Sitting Pretty.  No galling in making  up. Hardness-Differential, built into seats of Rockwood's new Union #603 does it!   Old 1955 petroleum industry advertisement. Would look sensational matted and framed!

Approximate size  9 x 12 inches.
