Yup. Marble. The later "version" of Tiger. I have seen a fair few earlier (early '70-'80s) shapes revived in this Marble colourway - and I have the massive globe that is photographed (very badly - the image is all washed-out) in the book.
They've revived the small squat round shape (as in this piece); stoppered decanters, both round and square in profile, tricorn bowls etc.
I don't know when the name change happened, and I don't actually know if it coincides with the design itself changing so much.
In Marble, there is a somewhat frothy, creamy, flat background, with deep brown speckles and flat ribbons of blues and browns.
It's been in production since the mid-'70s, either as Tiger or later, Marble.
In Tiger, the colours run much deeper into the thick walls of the vessel, overlap each other more, and there is often a deep yellow colour going through it - not this speckled flat creamy colour, although it can be slightly similar, the bubbles are marginally bigger and the colour is yellower.
It's one of these things that is hard to describe, but is absolutely obvious when you look at it.
I'll post some later, if you want me to Chris.
