How tall is it Bryn ?
I have seen some quite large ones for sale in the Canada... as well as UK - I think in this shape - Iti's hard to be sure from the angle of your pic.
If its what Im thinking of then it reminds me of the shape of the Toronto Tower.

Altho Homlegaard did some very large Gul vases ...I have my doubts that they made many other very large pieces.
The color is also bugging me. It's doesn't seem Holmegaard-ish but I could be wrong. I have an idea that Adam / DAvid555 knows more about this.
I'm not at all sure that it's Scandinavian. It could be .....but I have my doubts.
But you know at the end of the day it's a great piece in a fabulous shape. As glass researchers we tend to forget that people buy things because they like them. I was most tempted by the one I saw which was in a creamy yellow. Had it not been for the huge cost of shipping it from Canada I would have been more than tempted. Bryn I'm sure yours will do well.
