DESCRIPTION:

On this original linen-backed lithograph from 1932 (includes original specification sheet), Eclipse Aviation Corporation, a corporation of New Jersey, United States of America, patented an invention relating to the starting mechanisms for internal combustion engines, and more particularly the mechanism for use in starting aircraft engines.

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.
