A fabulously decorative vintage piece. 
These were used to make rubber gloves, by dipping the mould into a rubber solution and leaving to dry. The rubber was then rolled off the mould and et voila. . . it was a rubber glove. The machines these things were attached to can be seen in the photos. 
This particular mould is copper coated in tin, from America. 
These are just so decorative 
They look great on a mantle or as part of a vignette and truly lovely adjourned by jewellery.
