DESCRIPTION:

On this original linen-backed lithograph from 1932 (includes original specification sheet),

Phillips Petroleum Company patented improvements in flow heads for oil wells. Phillips Petroleum Company was an American oil company incorporated in 1917 that expanded into petroleum refining, marketing and transportation, natural gas gathering and the chemicals sectors.

On August 30, 2002, Conoco Inc. merged with Phillips Petroleum to form ConocoPhillips, becoming the third largest integrated energy company and second-largest refining company in the United States. The company moved its headquarters to Houston.

In 2012, ConocoPhillips split into two separate companies. The legacy company kept its name and spun off the midstream and downstream portions of its business. The new company, which owns the refinery, chemical and pipeline assets formerly held in ConocoPhillips, is named Phillips 66, the brand name and trademark used by the original Phillips Petroleum from 1930 until the 2002 ConocoPhillips merger.

All patent lithographs sold by Maymont Group are 100% ORIGINAL.

These documents are NOT reproductions or posters (patent art).

These are the original lithographs found in books obtained from the Patent and Trademark Office directly.

 

In the 1800's and early 1900's, inventors would submit a detailed drawing of the invention and/or improvements to the patent and trademark office. Once received and if approved, the Patent office would then send a letter of confirmation to the inventor and begin to take that drawing and etch it into stone in order to create and print this linen-backed lithograph. These documents are the original hard copies that were created by the patent office's artists, and act as patent examiner reference material. With that being said, these are 100% original and are the only physical copies in existence.
