Designed by Charles Boyton for John Dickinson and Co Ltd of England, this object was part of a larger set known as Carvacraft. Semi-circular and made of imitation amber Catalin, the trade name for a cast phenol formaldehyde resin, it has a square hollow in the middle and stepped curves decorate the sides. The production of desk accesories was a popular use for plastics, even in the earliest days of the industry when gutta percha and bois durci were used.
