At least I think it's glass. I picked this up with some other pieces as part of a job lot in South West England. Not really my cup of tea otherwise. I'm sure that I've seen it before somewhere but can't seem to track it down. Any pointers would be much appreciated although I would think "once seen, never forgotten" or maybe "once seen, best forgotton" probably applies. It stands about 9 inches (22 cm) high and is hollow, so almost certainly intended as a vase.
