It doesn't fit in with our other glass pieces as we tend to collect glass vases, bowls, and penguins rather than paperweights, so it's destined to go on ebay this evening.
I've taken some slightly better pics which are too large to go on to the message board. If they are of any use you are welcome to make use of them by copying them from the ebay listing, or send me a PM and I'll zap them to you via email.
