Accurate Description of Item
One Early 20th Century Celluloid Frog Pin
Appraiser Remarks
Based on what I can see in the images your Frog dates from the 1920's and is made of "Celluloid" , an early form of plastic. The name Celluloid actually began as a trademark of the Celluloid Manufacturing Company, first of Albany, NY, and later of Newark, New Jersey, which manufactured the celluloids patented by John Wesley Hyatt. Hyatt used heat and pressure to simplify the manufacture of these compounds. Over the years, celluloid has become the normal term used for this type of plastic. In 1878 Hyatt was able to patent a process for injection moulding thermoplastics, although it took another 50 years before it could be realised commercially, and in later years celluloid was used as the base for photographic film.
