Thanks m and Dirk.
Well done m I had a feeling it was French and when I said Baccarat I was also thinking possibly St Louis. I know the bust you are thinking of as I had a frosted bust of Christ by Baccarat which I sold but you can see a picture on Pamela's site .
I spoke to someone I know in the USA today who has a very large collection of this type of novelty items and he told me it was made by St Louis, it was made in 2 sizes and that he has 3 of them in the small size in purple slag and the rare pale blue slag, they also made the Small one with out the stepped base.
Thanks Dirk for the link I had a feeling it would be some where on that web site . I did have a quick look last night but very difficult if you do not speak German. A very comprehensive look at both sizes , variations and all the known colours and nice to know that some are marked.
