I don't have that one on my shelf, but I'll look up the references. Ta.
I'm also wondering if it might not be too off the wall to investigate Peter Shire as a possible designer, as it ticks a few of the boxes for his work (domes, or in the case of the larger versions, spheres, and serpentine shapes as a recurring theme, along with high-contrast colour combinations).
Not everything he produced for Vistosi was totally
crazy postmodernism, and not everything of his was signed (Design & Arts have, in fact, carried a few of his known works unsigned in the past).
