On this original linen-backed lithograph from 1889, Crookes, T. and Lomas, F. patented a guard for a razor comb making it safer to use. The blade is pivoted to the outer end of a comb guard to the center of which a handle is attached by a knife hinge so that the blade may either be set longitudinally or transversely. A cover slipped on the back of the blade when open prevents closure. It may then be used as an ordinary razor or sharpened in the ordinary way.

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.
