Thank you for all your replies and comments, it does disclose the many possibilities of a piece of glass that has been artisticly made by someone. 100% certainty of maker is not always possible but more so perhaps the studio itself. And at the end of the day do we personally like it, if so buy it and keep it, after all beauty is always in the eye of the beholder. I don,t like it because I favour not crowns and the colour co-ordination, but someone else will love it. £118 was about right I guess. Regards Roger.
