Patent model for printing on pyroxyline compounds (celluloid)

Description (Brief)
This patent model demonstrates an invention for variations on the method of printing celluloid under heat and pressure. The invention was granted patent number 348222. The model consists of three photogravure specimens.
John Wesley Hyatt (born 1837) started his working life as a printer. Early in his career, he took out a patent for a composition for artificial ivory billiard balls, which led him to the invention of celluloid in 1868. In 1869 Hyatt and his brother Isaac founded the Celluloid Manufacturing Company. He held some 250 patents, mostly concerned with the use of celluloid.
