My one and only piece is in greens and browns on a white background, much like Ronnie's piece.
It is a JIP, the centre part of the base is very highly indented, quite like lampwork. But it's packed away in one of the crates in the attic, I don't even know which one, I can't get at it.
I've had it since approximately 1999.
(ooops, there's the boxed "pink sugar" mouse, I'd forgotten about it already, but it doesn't really count as proper glass to me.)
