c1940's Early plastic Fish hook brooch. Not 100% sure of the technical name of this type of plastic and I beg you not to inform me of it as I won't have time to change the listing. Very well preserved authentic item from an extensive long time collection put together in the last quarter of the 20th century. Measurements shown in pics, it will not be available for extra measurements/pics until sold. Thank you so much for your time and consideration.
