Pneumatic Tire Foundation Dunlop Rubber Company Original Patent Lithograph 1932
On this original linen-backed lithograph from 1932 (includes original specification sheet), Dunlop Rubber Company Limited patented an apparatus for constructing the foundation of pneumatic tires. Dunlop Rubber was a multinational company involved in the manufacture of various rubber goods. Its business was founded in 1889 by Harvey du Cros and he involved John Boyd Dunlop who had (re-) invented and developed the first pneumatic tyre. It was one of the first multinationals, and under du Cros and, after him, under Eric Geddes grew to be one of the largest British industrial companies. J B Dunlop had dropped any ties to it well before his name was used for any part of the business. The business and manufactory was founded in Upper Stephens Street in Dublin. A plaque marks the site, which is now part of the head office of the Irish multinational departments store brand, Dunnes Stores.
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.
