Thanks a lot Christine, the links are useful. Henry Haig is the artist. It is amazing that an artist trained in the mid fifties was doing work like this until 2001, perhaps later. The glass seems difficult to locate in time (for me) and I imagined it could have been 1930's or 50's, but 1990's was a surprise. His style is distinctive and if I see it again, I will certainly recognise it. I wonder if he made any vases! The links give me some more venues to see his work perhaps, thanks again,
